A GC/FID instrument for BTEX monitoring in air, water and soil
The airmoVOC BTX is a gas chromatograph for the analysis and monitoring of trace amounts of benzene, toluene, ethylbenzene (m/p/o) xylene by FID detection.
Automatic sampling and concentration using an absorbent trap. Desorption from the trap and injection into a metallic capillary column regulated by a temperature gradient. The H2 pressure at the column head is controlled by a piezo valve.
The detection of all compounds eluting from the column is performed by a FID detector.
The airmoVOC BTX is equipped with an integrated PC comprising of the Vistachrom programme. The internal calibration allows automatic validation of results. (Certified Benzene tube at ± 10%).
The instrument is robust, compact and very low maintenance and offers excellent result quality: repeatability, linearity, stability and sensibility (ppt).
