Ambient air monitoring by FID detection – airmoVOC BTEX

Context & Challenges
Urban pollution is a problem that concerns more and more people in charge of public health. In large cities, car
emissions are an important source of atmospheric pollution. This problem is growing as the traffic keeps on
increasing. BTEX compounds are present in car emissions. It is therefore important to be able to analyze them
with short analysis cycle duration and on a continuous and automatic way.

Chromatotec® Solutions
The note presents the analysis of ambient air BTEX by trapping of the compounds on adsorbent.

The air is sampled at ambient temperature by a trap. This
system allows performing a pollution monitoring on a quasicontinuous mode (sampling during 75% of the time). The
trapped compounds are then thermo-desorbed.
The compounds are separated using a metallic capillary
column and detected with a flame ionisation detector (FID).
The analysis are treated by an integrated microprocessor, and
the results are transferred towards a PC where easy to use
software allows to visualise and to retreat the results if
necessary. Intern calibration systems allows for calibration
and validation of results.
