Analysis of Benzene, Toluene, Ethylbenzene, o,m,p Xylene, Styrene

A GC/FID instrument for BTEX monitoring in air, water and soil

Description :
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.

Principal :
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

Characteristics :
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).

MCERTS certified analyser for benzene measurement following EN 14662-3

VISTACHROM ® software :
Chromatotec developed software system allows :

  • Remote monitoring
  • Full traceability through archiving of results and QC
  • Set up and control of threshold alarms
  • Export of data MODBUS / MGS1 / 4-20mA /0-10V
