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

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
