The 530® FID BTEX Analyser detector is a carbon atom counter. A sample is introduced into a micro flame lit by hydrogen and air (1:10 ratio), where the electrical charges generated by the oxidation of Cx to CO are proportional carbon content in the sample. The electrical charges are collected by two polarised electrodes and converted by an electrical circuit into an electronic signal. The 530® FID BTEX gas chromatograph is intended for continuous monitoring of Benzene Toluene, Ethylbenzene and Xylene concentration in ambient and indoor air.

The same technology can be adapted to specific VOCs air quality monitoring. The coupling of gas chromatography separation with state of the art FID detector allows accurate and reliable measurement of Benzene (C6H6), Ethylene (C2H4), Propylene (C3H6), Styrene (C8H8), Acetone (C3H6O), Formaldehyde (CH2O) and many others VOCs in ambient and indoor air.
