The airTOXIC by Chromatotec is a GC-PID, MCERTS-certified analyzer for the continuous monitoring of BTEX in air, water, and soil. It uses a six-way valve, an absorbent trap, and a metallic capillary column. The instrument is equipped with a benzene permeation bench for in-situ automatic calibrations and can be used for emissions monitoring with a dilution system.
The airTOXIC gas analyzer features a rotary valve with a single absorbent trap and a 30-meter, 0.28 mm metallic identification column. It achieves a minimum detection level as low as 10 ppt for benzene or 1,3-butadiene (A76022) in ambient air. Its main characteristics include miniaturization, sensitivity, mobility, and flexibility. All components, from sampling to data storage, are integrated into a 5U 19″ rack.
