New standards in sample preconditioning

Filtration, dilution and settling.

From the sample take-off point to the analyzer The successful implementation of wet-chemical analyzers in process control

strategies could not have been achieved without the development of a new

generation of automatic sampling and sample preconditioning systems.

Pretreatment systems that can deal with the most difficult waste water

streams, complex matrices or the harshest chemical liquids? AppliTek offers

a solution to each and every preconditioning challenge:

• Filtration: from 0.04 µm up to 2 mm

• Dilution: for g/l measuring ranges

• Settling: for very high solids content or saturated liquids

Rationale behind sample preconditioning

Sample preconditioning is not restrained to simply filtration but consists of

several techniques to automatically precondition a sample. The importance

of appropriate sample preparation for an on-line analyzer system cannot be

understated. Even the best analytical techniques cannot rectify problems

generated by neglected sample pretreatment, and poor analytical precision

or analyzer failure often occur as a result of this.


Reduced maintenance

All AppliTek preconditioning systems are designed for fully automatic

operation and require virtually no human intervention. Basically all systems are

incorporated either with a blow-back action by instrument air, or a specific

cleaning cycle. This fundamental design principle does not merely allow

trouble-free sampling, moreover it contributes to high up-times. The design

and choice of materials of our systems is second to none and make them ideal

to be used in many applications, even for non-AppliTek analyzers.

Custom sampling and preconditioning panels Deeply rooted into the process industry, AppliTek has extensive experience

with a vast choice of pretreatment techniques. We not only know how to

handle and pretreat liquids but also slurries, powders and gasses. Therefore

we are able to modify our existing standard systems, or to engineer a new and

unique preconditioning panel in accordance to your specs.

Quality policy and trustability

In some cases, automatic self-cleaning sample preconditioning systems

may be as complicated as the analytical instrumentation to which they

deliver clean samples. Trustability is therefore the currency of exchange

between you and AppliTek. Our quality approach is visible in all steps of

the delivery chain, from the initial design up to quality control, adding a

proven track record of more than 25 years of analytical technology.

Clearly better solutions in sample pretreatment.


ModuSize® Self-cleaning Filtration System

Initially designed for larger travel streams, this classic AppliTek fast loop

filtration system already has a long track record of reliability and

strong operational performance. The stainless steel filter element is

available with various pore sizes which makes it an ideal solution for

pretreating wastewater and industrial effluent prior to analysis. While

ModuSize® is available as a standard filtration panel, it can be integrated

in many customized filtration systems in analyzer cabinets and shelters.

Analyzer

Filtration scheme, left: Example of a custom ModuSize® filtration panel with double fast loop circuit for separate sample pretreatment. Also visible: filter units, static pressure regulators, valves and collective drain. There are two ways to control the ModuSize®: equipped with a built-in PLC, the system can operate autonomously, even in remote location. The version without PLC uses the PLC of an AppliTek analyzer and needs to be installed on the same location as the analyzer.


Buffer container A buffer container with a compact footprint and elaborate design can be included in your design. This not only allows a quicker refreshing of the sample buffer volume, but

also airtight sealing against possible odours or gases,

and the possibility to insert a level detection.

Cleaning principle Instrument air is injected continuously through a central aeration element located at the bottom of the filter. The air bubbles cause turbulence at the surface, which prevents

solids to stick to the membrane.

This list serves to illustrate the complex interactions that may take place in

liquid samples, due to physical qualities and composition. It is a valuable

tool that allows you to collect data on the sample’s characteristics and

check carefully whether a sample preconditioning is needed, and if so,

which system within AppliTek’s standard range would be recommended.
