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-ionization detector (PID). This compact and fully automated analyzer provides equal performance to the laboratory chromatographs and is particularly well-suited for fixed or mobile
ambient air quality monitoring stations.

Features

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 analyzer 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
Ultra fast 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
Equipped with LCD screen
High sensitivity, stable and linear response PID detector
Long-life capillary column
Self-contained and completely automated
Synoptic flow diagram display
TUV Compliant following EN 14662-3
