▪ On-line and on field monitoring (not only lab)

▪ Speciation of VOCs & Sulfur compounds

▪ Automatic data validation

▪ Standalone solutions (no need of gas cylindersor specific standards during routine use)

▪ Design of solutions (GC-PID, GC-FID, GC-TCD,

GC-FID-MS, GC-FPD or GC-SSWCD, FTUV and more)

▪ Tracking ppb/ppt concentration levels in air orprocess

▪ Tracking up to % concentration level for specificprocess

Our specificity


• Formaldehyde is present in :

- Chemical, pharmaceutical, funeral industries

- Paper plants

- Indoor air (paintings, coatings)

• Formaldehyde effects :

- Irritating, breathing issues ( <500 ppb)

- Carcinogenic ( >500 ppb)

- Risk of death ( > 20 ppm)

Measurement principle : GC FID

Sampling trap Metallic column Flame Ionization Detector(FID)

➢ Separative method

➢ Identification with retention time

➢ Linearity for every concentrations range


10

airmoHCHO external overview

Air flow regulator for flame

Pressure regulator for carrier gas flow on the column

H2 flow regulator for flame

Injection valve 6-ports withsampling trap and pre-colulmn

Methanizer

Oven with programabletemperatude and metalliccolumn inside

Permeation oven

FID Detector


12

Measurement principle : analysis cycle

• Sampling step :

- Pre concentrate VOCs in the trap

- Realized at the end of analysis cycle to reduce cycle time

• Analysis step :

- Injection of trapped VOCs in the column by thermo desorption

- Separation in analytical column

- Mehanization of VOCs

- Detection by FID


13

Methanization

• Principle

- Transform aldehyde compounds such as formaldehyde to methane

- Using ruthenium for catalyse

• Advantages

- HCHO has a bad response with FID Detector

- CH4 is well detected by FID


14

Step 1 : Thermo-desorption

TRAP CH4

H2

Pre-column Metallic column

Methanizer FID

VOCs + formaldehyde


15

Step 2 : First separation

Results for permeation tube analysis

• Configuration permation tube :- [HCHO] = 3028 ppb- Gas Temperature : 90°C- Gas flow : 83.3 ml/min- Sampling time : 300s- Acquisition time : 420s

• Results :- [HCHO] = 3035 ppb- Theorical deviation : 0,2%


20

Ambient air analysis

• Cycle time : 30 min• Concentration : 32.6 ppb• Limit of Detection : 3.8 ppb


21

Advantage of this solution

➢ Short cycle time (30 min) compared to ISO 16000-3:2011

➢Automatic solution

➢ Few interferents with chromatography

➢ Visualisation of data


22

Conclusion

➢ Crucial need to monitor formaldehyde

➢Using GC-FID for online measurement

➢ airmoHCHO is a fully autonomous system

➢ Possibility to measure acetaldehyde methanol and ethanol in addition
