The VOC72M’s metrology, in accordance with EN 14662-3 (2005) & EN 15267-1 (2009) standard for benzene measurement, is based on gas chromatography (GC) coupled with a photo-ionization detector (PID).
Compact and fully automated analyser providing equal performance to the laboratory chromatographs; particularly well-suited for fixed or mobile ambient air quality monitoring stations.
Quick check of the chromatograms possible directly on-screen, without the use of a computer
