VOC72M Gas Chromatography Volatile Organic Compounds (BTEX) Analyser for Ambient Air Quality Monitoring

Environnement S.A (France) launches the most compact and fully automated analyser, providing equal performance to the laboratory chromatographs and particularly well-suited for fixed or mobile ambient air quality monitoring stations.

The VOC72M’s metrology, in accordance with EN 14662-3 standard for benzene measurement, is based on gas chromatography (GC) for the separation of the measured compounds coupled with a photo-ionisation detector (PID).

Exclusive features include: Robust and low maintenance instrument (no PID lamp cleaning), Ready to use in less than 30 minutes, Performs all the functions, such as: sampling, analysis and data management, in a simple and completely autonomous mode, Quick check of the chromatogram peaks possible directly on-screen, without the use of a computer, Memory effect (up to 10 times lower than required by the standard EN14662-3) allowing the automatic calibration of the analyser on a single cycle without an external PC, GC column equipped with an innovative liquid-cooler; retention times are stable even with a fluctuating temperature, Ultrafast trap heater (heating rate >160°C/second), Remote diagnosis, made possible without opening the hood, Replacement of the trap in less than 2 minutes. No adjustment required, Use of a single gas source (nitrogen), 3 levels of built-in security, High sensitivity, stable and linear response PID detector, Long-life capillary column, Self-contained and completely automated, Synoptic flow diagram display and TUV Compliant following EN 14662-3

Major fields of application include: Ambient air monitoring, Monitoring of industrial sources emitting VOCs and Photochemical pollution studies (stationary and mobile laboratories)
