Automatic Chromatographic Analyzer ACA BTEX Modification for Accurate Measurement

Analyser chromatographic automatic ACA modification BTEX is designed to measure mass concentrations of: benzene, toluene, ethylbenzene, m-xylene, p-xylene, o-xylene, chlorobenzene, styrene, dimethylbenzene (mixture of o-, m-, p- isomers) in atmospheric air. Measurement range of mass concentration from 0.005 to 6.0 mg/m3 (for dimethylbenzene from 0.015 to 18.0 mg/m3). Relative error tolerance limits: ±20%.

The analyser is a stationary instrument, single unit, equipped with a 10-inch touch screen display for control and indication of measurement results. The operating principle of the analyser is based on sample pre-concentration, chromatographic separation of sample components and photo-ionisation detection. The analyser is a measuring instrument of approved type.
