6 Putting CarboQC into Operation


6.1 Installing CarboQC

CarboQC can be used in the laboratory as well as at-line. In any case, sample has to be transferred into the measuring chamber of CarboQC without the loss of carbon dioxide during the transfer. Subsequently, the installation of CarboQC in combination with a PFD Filling Device is described.

The PFD Filling Device pierces the bottle closure or the base of the can and forces the beverage into the measuring chamber of CarboQC using compressed gas (6±0.5 bar relative/87±7 psi). In the unlikely event that a bottle or can bursts, the operator is protected by a safety shield which is moved vertically over a bottle or can. A safety pin on the bottom of the safety shield ensures that the system cannot be pressurized as long as the safety shield is not in the protective position.

NOTICE • Do not operate CarboQC without the filter being installed (see Fig. 6 - 1).• Do not place CarboQC on a wet or humid bench because humidity entering

the housing could damage the instrument.

TIP If required, fasten the PFD Filling Device to the bench with clamps using the opening in the front of the base plate or with a bolt through the corresponding hole in the base plate.

WARNINGBursting bottles/cans may damage the safety shield and chippings may be hurled through the gap at the rear of the safety shield. Injuries, especially of eyes and face, and hearing damage possible. • If a container bursts, chippings may be hurled through the gap on the back

of the PFD Filling Device. Therefore place the PFD Filling Device with a distance of 0.5 m (20 inches) with its back to the wall. The PFD Filling Device has to be placed so nobody can stand between the PFD Filling Device and the wall.

WARNINGCompressed gas is used. Loose hoses may lead to injuries, especially of eyes and face.• If CarboQC is operated in combination with a PFD Filling Device, do not

activate the compressed gas supply before all hoses are properly connected.

18 C26IB001EN-A


Compressed gas supply

CarboQC and PFD Filling Device are best operated with compressed air. In case a dissolved oxygen meter is also connected, use compressed nitrogen as compressed air might influence the oxygen result.

If there is no in-house supply of compressed gas available, the PFD Filling Device can also be operated with compressed gas from a gas cylinder.

The hoses of the PFD Filling Device have an outer diameter of 6 mm. If the compressed gas outlet does not match the required diameter for PFD Filling Device operation, check for pressure adapters at your local supplier.

Mounting the hoses

For the hose connections between CarboQC and PFD Filling Device, use the delivered polyurethane hose 2.5 x 4 mm.

NOTICE Keep the hoses between the instruments as short as possible. This reduces sample consumption as well as the risk of CO2 diffusing through the hoses thus influencing the results.

To connect a hose

• To connect a hose to a fitting, push the hose into the fitting as far as it will go.

TIP When reconnecting a hose, cut off a few millimeters of the hose if the color of the hose is changed to achieve tight seal.

To disconnect a hose

• To remove the connection, press the ring of the fitting towards the fitting and then pull out the hose.

NOTICE Only take apart connections if it is really necessary to do so as frequent handling may destroy the fitting.

2. Connect a polyurethane hose 2.5 x 4 mm of approx. 100 mm (4") length to the outlet of the filter and the sample inlet (5) of CarboQC.

3. Connect a polyurethane hose 2.5 x 4 mm to the sample outlet (6) of CarboQC.

4. Connect the T-hose connector 4 mm (supplied with CarboQC) to the other end (7) and put it into the waste vessel.

5. When all hoses are connected properly, activate the compressed gas supply.

6.2 Switching the Instrument on and off

NOTICE Before connecting the power adapter to the mains and switching the instrument on, make sure that the correct line voltage is available (AC 100 to 240 V, 50 to 60 Hz). If large voltage fluctuations are to be expected, we recommend using a constant voltage source (UPS).

WARNINGSerious injuries are possible due to high voltage at parts of the instrument/measuring system unless the following instructions are followed: • Make sure that the non-fused earth conductor of the power cord is

connected to earth.• For proper insulation to the mains only use the original power adapter

which is supplied with the instrument.• The power adapter is not suitable for operation under wet at-line or

outdoor conditions! Do not connect the power adapter of CarboQC to the mains under wet ambient conditions.

8 Measurement

8 Measurement

8.1 Preconditions

CarboQC determines the amount of dissolved carbon dioxide in a beverage. To get a correct measurement, the instrument has to be in good working condition (see Chapter 9.2).

In addition, the sample package has to be in equilibrium. As carbon dioxide in a package can be found in the liquid phase as well as in the head space, equilibration is essential for repeatable and well defined measurement results. Equilibration can be achieved by gently shaking the bottle horizontally about 15 times back and forth. This will ensure that the net transfer of CO2 between liquid and head space is zero, in short, in equilibrium.

8.2 Preparing CarboQC

CarboQC is equipped with 7 standard methods to account for the different solubility of carbon dioxide in different beverages (see Chapter 13.1.1). The selected method is displayed in the top left corner of the display and has to be selected manually prior to a measurement by pressing the <Method> key, selecting the desired method and confirming with <Enter>.

If necessary, press <Method> on CarboQC to select the appropriate method for the sample to be measured from 7 standard methods or 17 customer-specific methods. For customer-specific methods, see also Chapter 13.

The 7 standard methods are:

The standard methods do not compensate for any temperature effect that influences the CO2 distribution between headspace and liquid of the bottles or cans. Therefore, they should only be applied within a small range (e.g. ±3 °C/5 °F around reference temperature) of package temperatures.

24 C26IB001EN-A

8 Measurement

Compensation of the headspace-related temperature effect and therefore measurements in a wider range of package temperatures can be achieved with the 17 customer-specific methods once they are properly set up. For more information, see Chapter 11.2.5.

8.3 Transferring the Sample into the Measuring Chamber

Sample transfer always carries the risk of loss of carbon dioxide or introduction of other dissolved gases. Thus, sample transfer is best performed in combination with a filling system that avoids these risks.

The PFD Filling Device is equipped with a seal to close off a small area of the package, bottle or can. This small area is pierced with a knife to allow introduction of a sample tube.

Applying pressurized gas to the head space of the container allows the transfer of sample to the CarboQC measuring chamber without the loss of CO2. Subsequently, the measurement of CO2 with CarboQC in combination with a PFD Filling Device is described in detail.

TIP Piercing the package with a PFD Filling Device might result in the pierced disk falling into the container. The filter between PFD Filling Device and CarboQC will keep this particle from entering the measuring chamber.

8.4 Measurement Using the PFD Filling Device

8.4.1 Setting the Correct Flow

The flow through the measuring chamber should be such that 100 to 150 mL of sample are consumed when the filling time is set to 20 seconds. Considerably lower or higher flow rates may cause erroneous measurements due to sample carry-over or gas bubbles in the measuring chamber.

8 Measurement

To adjust the flow, insert a suitable tool (e.g. screwdriver, ... ) into the cavity of the flow valve and turn it clockwise for decreased and counterclockwise for increased sample flow.

With a graduated vessel

1. Use a beaker or graduated cylinder to check the correct flow.

2. Insert the T-hose connector of the sample outlet hose into the beaker.

3. Select the menu "instrument > rinse" and set the rinsing time to 20 seconds.

4. Position the flow valve (see Fig. 8 - 1) at about 10% flow, i.e. close to the minimum flow position.

5. Carry out a measurement as described in Chapter 8.4.2.

6. Check the volume of liquid consumed: It should be 100 to 150 mL.

7. If the volume is not in the required range, slightly open or close the flow valve (see Fig. 8 - 1) and repeat steps 5 to 7 until the volume/weight is within the required range.

With a marked bottle

1. Make volume markings "0" and "150 mL" on a transparent 0.5 L (16 oz) or similar size PET bottle.

Use water and a graduated cylinder or a balance to correctly place these markings on the bottle.

2. Fill the bottle up to the "0" mark with deionized water and close it.

3. Insert it into the PFD Filling Device.

4. Perform steps 3 to 7 as described above.

Via weighing

1. Weigh a full beverage bottle or can and make a note of the weight.

2. Insert the package into the PFD Filling Device.

3. Perform steps 3 to 5 as described above.

4. Remove the package from the PFD Filling Device and weigh it again.

The weight should have decreased by 100 to 150 g.

C26IB001EN-A 27

8 Measurement

The measuring chamber is first rinsed and filled with 100 to 150 mL of the new sample.

2. Check the measuring chamber visually for bubble-free sample flow.

It must be free of bubbles before the actual analysis starts. If the bubbles do not disappear after approx. 15 seconds, clean the filter (see Chapter 10.3).

3. Check the pressure of the compressed gas supply. It shall be 6±0.5 bar relative (87±7 psi).

Once the rinsing is finished, the analysis will start. The piston will move down to a first halt and then to a second halt with the stirrer permanently in operation.

NOTICE If the sample has a high content of particles (e.g. pulp), the sieve of the filter tends to clog. This will lower the pressure in the measuring chamber. Check the pressure indicated at CarboQC during sample filling. When using a PFD Filling Device, the pressure should not go below 5 bar/70 psia. If the sieve is completely clogged, bubbles and foam form in the hose between filter and measuring chamber and in the measuring chamber itself. Clean the filter as described in Chapter 10.3.

4. Wait approx. 90 seconds for the measurement result.

The measurement result will be displayed, stored in the memory and optionally printed out. The piston will then move up, but the measuring chamber will remain closed.

TIP If a measurement was carried out with an incorrect method, the current result can be recalculated using the correct method as long as this result is still displayed. Press <Method>, select the correct method and press <Enter>. The recalculated result will be shown on the display. To store and optionally print out this recalculated result, press <Print>.

At the PFD Filling Device

1. Move the sample tube up to the highest position and fasten it.

2. Push the activating lever to de-energize the system.

3. Move the safety shield up to the highest position and remove the package.

4. If the package sticks to the piercer, rotate it counterclockwise and pull it down simultaneously.

5. Optionally, check with a balance whether the correct amount of sample was taken from the bottle or can.

Now CarboQC and the PFD Filling Device are ready for the next measurement.

6. If no further measurements are performed, clean the system (see Chapter 10).

8.5 Checking for a Correct Measurement Procedure and Avoiding Errors

Zero point checks

Regular zero point checks of CarboQC with deionized water are recommended to survey faultless functionality of the instrument. The water check with CarboQC, when carried out correctly with deionized water, is the precondition for a correct measurement result. The result has to be 0± 0.02 vol (0± 0.03 g/L).

If the zero point check and adjustment are carried out with water that contains CO2, the consequence will be an unjustified offset. Consequences are systematic errors of results.

Sample equilibration

Only transfer equilibrated sample to the measuring chamber of CarboQC. If samples are not equilibrated (shaken) prior to analysis, the consequence might be erroneous results or poor repeatabilities.

Correct measurement method

Check whether the correct measuring method is chosen on CarboQC. A wrong method will lead to a wrong result.

Correct sample flow

Check the correct flow. The volume consumption per measurement is recommended to be 120 to 150 mL, and for identical samples at least 100 mL. Too low sample volume consumption causes sample carry-over.

Correct filling pressure

The filling pressure displayed on the CarboQC display has to be 5.5 to 6 bar relative (79 psi to 87 psi) and the measuring chamber has to be filled without bubbles. Too low sample pressures during sample filling causes bubbles in the sample chamber. As a consequence, the starting volume will consists partially of gas bubbles thus yielding incorrect results.

Measuring chamber filled without bubbles

Bubbles in the measuring chamber can falsify the result. The most common cause for bubbles is a clogged filter. To clean the filter, see Chapter 10.3.

30 C26IB001EN-A

9 Checking the System


9.1 Influencing Factors

Mechanical functionality of CarboQC is essential for a correct result. CarboQC has three parameters that act as a precondition for a correct result.

• pressure• temperature• volume expansion of the measuring chamber

9.2 Zero Point Check

A zero point check is necessary before starting the determinations. The zero point check is a measurement with deionized (or distilled) water. The CO2 result has to be 0±0.02 vol (0±0.03 g/L).

The deionized water must not contain any dissolved carbon dioxide and is ideally free of ions such as calcium that could cause deposits in the measuring chamber of CarboQC.

Sometimes, deionized water contains CO2 absorbed from the ambience and CarboQC displays the amount of the CO2 absorbed. Either heat up and boil the water and cover it up while cooling down or do the water check with tap water. In case of using tap water, rinse the measuring chamber with deionized water afterwards.

In case the measurement of deionized water does give a CO2 reading out of tolerance, always check the water first before inserting a pressure offset (see Chapter 9.5) into CarboQC.

In general, the zero point check with CO2-free water is sufficient to ensure correct functioning of the instrument in-between service intervals.

9.3 Check with Carbonated Liquid

Sometimes checkups are required with test samples at elevated carbon dioxide contents. Usually these checkups are provided within the periodical service and maintenance procedure. In case more frequent tests are required, continuous surveillance can be performed on a day-to-day basis.

There are two ways to perform an instrument check with carbonated liquids.

The first is the use of a CO2 standard. This procedure shall only be carried out by an authorized Anton Paar representative or service technician.

The second is the use of a control chart and internal standards.

C26IB001EN-A 31


NOTICE Only use cans as internal standards. Do not use bottles as their CO2 content might change.

Cans of diet soft drink or other cans of a non-sucrose based, non-inverting soft drink with > 3 vol (6 g/L) CO2 content are suitable to be used as internal standards.

If filling cans, provide 36 cans for initial preparation of the standards plus a sufficient number of cans for one check measurement per day over the time span between instrument calibrations by Anton Paar service representatives. Only use cans from the same production minute(s).

If purchasing cans, make sure that the required number of cans is from the same batch.

To prepare internal standards

1. Immediately after calibration of CarboQC by an Anton Paar service representative, draw 6 cans from the beginning, 6 cans from the middle, and 6 cans from the end section of a production run and measure them.

2. Calculate the mean values for every 6 measurements for the beginning, middle and end sections.

The 3 mean values may only differ by ±0.02 vol (±0.04 g/L).

3. If the mean values are suitable, provide a sufficient number of cans from this production run to be kept as internal standards.

4. If the mean values are not suitable, measure another 3 times 6 cans as above.

5. Determine the 3 mean values of the 12 respective measurements (for each mean value take the 6 measurements from the first selection plus the 6 measurements from the second selection).

These 3 mean values may only differ by ±0.015 vol (±0.03 g/L).

6. If the mean values are suitable, provide a sufficient number of cans from this production run to be kept as internal standards.

7. If the mean values are not suitable, the cans are not suitable as internal standards and cans from a different, more stable production run have to be used.

To draw and use the control chart

1. Calculate the mean m and standard deviation sd of all 18 (or 36) measurements.

The standard deviation shall be 0.025 vol (0.05 g/L) maximum based on the above limitations.

32 C26IB001EN-A

2. Draw a control chart with sample number on the x-axis and CO2

concentration on the y-axis ranging from (m - 3 * sd) to (m + 3 * sd) as the control limits.

3. Draw control limit lines, mean line and auxiliary lines as appropriate. This can either be done on paper or using a suitable computer software.

4. Measure one can of the internal standards per production day and draw a corresponding point in the control chart.

5. If a clear trend away from the mean becomes visible over time or the control limit of 3 * sd is exceeded successively, call for service immediately.

9.4 Beginning of the Shift/Day

Check for the correct sample flow with deionized water. A volume of 100 to 150 mL is

recommended.NOK → Adjust the sample flow.

See Chapter 8.4.1.

↓ NOKContact your Anton Paar representative.

C26IB001EN-A 33

9.5 Entering a Pressure Offset

With the menu "auto p-offset", an offset for the pressure sensor can be determined semiautomatically. Enter a pressure offset if the CO2 result of a zero point check with deionized water is out of specification (see Chapter 9.2).

TIP Sometimes, deionized water contains CO2 which has been absorbed from the air, and this CO2 content is displayed. Before carrying out an automatic pressure offset, make sure that the displayed CO2 is not caused by the water, but by the pressure sensor. Boiling and cooling the water before measurement will eliminate dissolved CO2.

Example:

A zero point check with deionized water yields (even after cleaning the system) a CO2 value of 0.05 g/L. The maximum allowed deviation for deionized water is 0.03 g/L. Therefore, the pressure sensor must be adjusted:

1. Select the menu "adjustment > auto p-offset".

In the first line, the previously measured CO2 value (0.05 g/L) is displayed. In the second line, the pressure value is displayed (e.g. +0.020 bar).

2. Press <Enter>.

The displayed CO2 value flashes.

3. Change the CO2 value using the <t> and keys until the value is inside specification (0 ±0.03 g/L).

The pressure value is changing corresponding to the CO2 value.

4. When the required CO2 value is displayed, press the <Enter> key.

The newly calculated pressure offset is automatically stored in the CarboQC memory and is used for subsequent measurements.

5. To change to the measuring window, press <ESC> three times.

12 Technical Background

12 Technical BackgroundThe working principle of CarboQC is based on the Multiple Volume Expansion Method and allows the determination of the true CO2 content.

Fig. 12 - 1 shows the principle of the Multiple Volume Expansion method for eliminating the influence of dissolved air or nitrogen on the measuring result: The CO2 content is measured at two different volume expansions of the measuring chamber, i.e. at 10 and 30%. If the two results are identical, there is no dissolved air or nitrogen present and therefore no correction is required. Dissolved air or nitrogen makes the second result lower than the first. The difference between the two results is used to calculate a correction which completely eliminates the influence of dissolved air or nitrogen on the measuring result.

13.1 Available Methods with CarboQC

13.1.1 Standard Methods

The 7 standard methods do not allow to change any parameter at all. It can be seen from Chapter 8.2 which method is recommended for which beverage sample. These methods do not provide any means for compensating temperature effects due to the headspace volume of beverage packages. They are therefore suitable for determining the true dissolved carbon dioxide content at a given package temperature.

13.1.2 Customer-Specific Methods

CarboQC provides 17 customer-specific methods. 7 methods, ending with "c", use solubility coefficients identical to the standard methods, and 10 customer-specific methods CMxxPROD also allow the entry of the solubility coefficient.

The 7 user-specific methods are named identically to the standard methods with additional letters "cc" to obtain eight digits altogether (DIETcccc; SPARKLcc and so on). These 7 methods allow modification of the constants k0 to k7, but these six methods do not allow access to the solubility coefficient for CO2 in the respective sample. The solubility coefficients in these user-specific methods are identical to the ones in the respective standard methods. The coefficients k0 to k7 can be used to compensate headspace related package temperature effects and to adapt the measurement results to those based on customer-specific solubility tables or formulae.

There are also 10 CMxxPROD methods; xx = 01, ..., 10. These 10 customer-specific methods allow the modification of the constants k0 to k7, but also the alteration of the solubility coefficient ks of CO2 in the sample.

13.2 Establishing Customer-Specific Formulae

13.2.1 Converting the CO2 Result into a Customer-Specific Result

In the customer-specific methods the calculated g/L results can be converted for user-specific CO2 tables or formulae. This conversion can also correct the temperature-dependent changes of the dissolved CO2 content resulting from the headspace to liquid volume ratio of the bottles or cans.

50 C26IB001EN-A

13 CarboQC Methods

This equation is used for custom-tailoring a CO2 result from the original CO2content c as determined by CarboQC.

Ccust is the customer-specific CO2 result. It is the modified carbon dioxide content that is calculated and displayed when customer-specific coefficients are used.

k0 will always be added to the result c. The factory setting of k0 = 0.

k1 is a multiplication factor. The factory setting of k1 = 1.

k5 is a reference temperature that needs to be keyed in if the result is to be related to a specific temperature. The factory setting of k5 is zero, which means that k5equals 0 °C, regardless of the temperature units selected in the menu.

A simple way of applying a reasonable temperature correction for the headspace influence is to use the customer-specific methods in CarboQC, rename them properly and set k5 equal to the average measuring temperature, and for k2 a value of 0.003 (typical range: 0.002 … 0.004) to get the temperature compensation to take effect.

k3 and k4 can be used for better fine tuning of the final customer-specific result. The factory setting is 0.

Example:

If the result given by CarboQC is 3 g/L and the desired or expected result is 3.3 g/L, there are two ways CarboQC can be programmed in order to transfer the CarboQC result into the customer-specific result:

(1) k0 is set to 0.3

The value ccust will be 0.3 g/L higher than the CarboQC result. This will also affect the zero determination with deionized water. A k0 of 0.3 will cause an offset as all results will be 0.3 higher than the determined value: instead of 0 the displayed result will be 0.3; instead of 2 the displayed result will be 2.3 and so forth. Therefore setting a positive k0 offset is a reasonable means to adapt the CarboQC results to readings of previous methods which were offset by a fairly constant air content of the samples.

Ccust .......................... Customer-specific CO2 result [g/L]

k0, k1, k2, k3, k4 ........ Customer-specific coefficients

k5 ............................. Reference temperature [°C]

c .............................. Original CO2 result [g/L]

t ............................... Measured temperature [°C]

Ccust k0 k1*c k2*c* t k5–( ) k3*c* t k5–( )2++ k4*c2+ +=

C26IB001EN-A 51

13 CarboQC Methods

(2) k1 is set to 1.1

The CarboQC result will be multiplied by 1.1. Instead of 3 the result will be 3.3 and instead of 2 the result will be 2.2. If the zero point adjustment works correctly, the zero reading will be close to zero and multiplication by 1.1 will not affect the zero reading noticeably. As an example, a factor of approximately 1.1 is often necessary if the customer-specific solubility table applied is actually a CO2solubility table for water, but it is applied to 10 °Brix soft drinks.

13.2.2 Converting the CO2 Concentration into a Customer-Specific Unit

For all customer-specific methods, the measured CO2 concentration can be converted from g/L into a customer-specific unit.

Proceed as follows:

1. In the menu "methods", select the desired customer-specific method.

2. Select the menu item "unit" and enter a name for the desired unit (maximum length of 6 characters).

3. In the menu "methods", change the coefficient "k1" so that the desired conversion is applied. E.g. setting k1 = 2, results in multiplying the result by 2.

4. Change to the measuring window and select the changed method using the <Method> key.

The newly set unit is displayed in the line for the CO2 content. When measuring, the conversion is carried out according to the entered coefficient and the calculated result is displayed.

5. The factor "fu" is a division factor which divides a customer-specific polynomial. E.g. using fu = 1.976 leads to converting the measurement result from g/L into vol.

13.2.3 Using a Customer-Specific Solubility Coefficient

The 10 CMxxPROD methods allow entry of k1 to k7 and, in addition, the solubility coefficient ks in g/(L * bar) at a temperature of 20 °C. These 10 methods need to be used when a sample does not match the ranges as given in Chapter 8.2; e.g. 1.61 g/(L * bar) for a 5 ±2 °Brix soft drink.

13.3 Transformation of the Determined Air Content

The following formula serves two purposes:

1. It allows to correct the ppm result with a different slope k6.2. It allows to compensate for the temperature dependent gas distribution in the

beverage container using k5, k7. The term in brackets is set to 1 if k7 ≤ 0.

This formula is used if the "air ppm" result needs to be corrected or the amount of gas in the head space needs to be taken into consideration. ctrans is the air content as a function of head space.

The factory setting for the "slope" k6 is 1.

cair is the air content in ppm as determined by CarboQC.

k5 is the reference temperature and Lb2 is the solubility of air at the determined measuring temperature T2[K].

Lb(k5) is the solubility of air at the reference temperature k5. This value can be taken from a table.

k7 is the head space to liquid ratio of the beverage container. If k7 ≤ 0 then the term in brackets equals 1; if k7 > 0 then the term in brackets is calculated.

Ctrans ........... Air content as a function of head space

k5 ............... Reference temperature [°C]

k6 ............... Slope

k7 ............... Headspace to liquid ratio of can/bottle

cair ............. . Air/nitrogen content in ppm as measured

T2 ............... Measuring temperature [K]

13.4 Calculation of the Package Pressure at a Reference Temperature

The 10 CMxxPROD methods CM01PROD to CM10PROD not only allow entry of coefficients k0 to k7 and ks, but also of the coefficients ka, kb, kc and kd. The coefficients ka, kb, kc and kd can be modified if the package pressure, determined at sample temperature, needs to be converted into the package pressure at a reference temperature.

TIP The value for the pressure at a reference temperature pref can be obtained as relative pressure if the ambient pressure in [bar] is keyed in. If kd is zero, the obtained value of pref will correspond to the absolute pressure.

Example: Calculation of the relative reference pressure of sparkling wine at 20°C (68°F)

1. Select the menu "methods".

2. Choose any CMxxPROD method.

3. Re-name the method and give it a significant denotation, e.g. SPARKL20.

4. Leave "fu = 1".

5. Leave "k0" to "k4" and "k6" to "k7" unchanged.

6. Select the reference temperature "k5" and change the entry to "+20.0000".

When setting "k5", always enter the numerical value of °C, even if the unit F is selected.

7. Set "ks = 1.51" (ks for SPARKL is 1.51 g/(L*bar)).

pref .............. Package pressure at reference temperature

pt ................ Package pressure as determined by CarboQCka ................ Conversion factor for pressure unit

Factory setting = [bar]. If the unit [bar] is desired, set ka = 1.

kb, kc ........... Factor for temperature compensationFactory setting: +0.00000Recommendation: kb = -0.028 (negative sign!) and kc = 0.00075

8. Set "ka" to "kc" as follows:

• ka = 1• kb = -0.028• kc = 0.00075

9. Change the preset value of "kd" and enter the average ambient pressure in [bar].

Then

pref, 20 = 1 * {ptas determined at t * [1 - 0.028 (t - 20) + 0.00075 * (t - 20)²] - 1}

C.2 Measurement

NOTICE Do not disconnect any hoses from CarboQC during the measurement.

TIP The minimum pressure for at-line operation of CarboQC has to be 0.5 bar (7.2 psi) above saturation pressure of the dissolved gases. Proper functioning is best determined by practical tests.

1. Press the <Method> key on CarboQC and select the required method.

2. If necessary, change the sample number by pressing the <Sample> key.

3. Open the sample valve of the line or tank.

4. Start the measurement by pressing the <Start> key on CarboQC.

5. Watch the measuring chamber.

After approx. 15 seconds rinsing time it should be free of bubbles.

TIP If the system pressure of the line is too low, the measuring chamber will not be free of bubbles in time. Fill the measuring chamber of CarboQC manually by pressing the <Rinse> key before pressing <Start>. After the measuring chamber opens,

• press the <Rinse> key periodically to turn the stirrer on and off,• make sure that a minimum of 100 mL flows through the measuring

chamber,• make sure the measuring chamber becomes free of gas bubbles.

The measuring result is automatically displayed after approx. 90 seconds and stored in the memory of CarboQC (max. 99 measuring results).

C.3 Cleaning the Measuring Chamber

By connecting CarboQC to a tap with process water

• Attach the inlet valve of CarboQC to a tap with process water (NOT with tap water as the limestone might harm the inlet and outlet valves).

• Then hit the <Rinse> key on the instrument to open the valves and rinse the measuring chamber.

With a peristaltic pump

• Connect the outlet tubing of a peristaltic pump to the filter or at-line adapter that is connected to the inlet valve of CarboQC.

• Hit the <Rinse> key on CarboQC.

C26IB001EN-A 61

• Then operate the pump as required and rinse the measuring chamber with detergent and/or deionized water. If detergent is used, the measuring chamber has to be rinsed carefully with process water or deionized water afterwards.

Appendix F: Troubleshooting

Appendix F: TroubleshootingQ The CO2 reading of the water check with deionized water shows >0.03 g/L CO2.

A Sometimes, deionized water contains absorbed CO2 and displays the amount of CO2 absorbed. Either heat up and boil the water and cover it up while cooling down or do the water check with tap water – but do not forget to rinse the measuring chamber with deionized water afterwards!

Q The CO2 reading of the first sample after a water check is low.

A If you go from samples containing very low to very high CO2 contents, the first result for the high CO2 content is slightly lower than the following ones. If only limited amounts of sample are available, it is a good idea to condition the instrument by e.g. measuring mineral water after the water check before measuring the first sample.
