Description
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 analyzer 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
