Using gas chromatography, the model airmoBTX 1000 measures the amount of Benzene, Toluene, Ethylbenzene and Xylenes in the air from sub-ppb levels up to 1,000 ppb.

Miniaturization, sensitivity, mobility and flexibility are the main features of the airmoBTX 1000. Everything from the sample port up to the data storage is integrated in a 19″-rack 5U. The airmoBTX 1000 uses a port valve with a single absorbent trap and a metallic 0.28 mm ID column. It has a programmed gradient temperature of the oven and pressure/flow control of the carrier gas by a piezo valve.

The detection is made with a Flame Ionisation Detector for high stability and an excellent sensitivity. Its minimum detection limit is as low as 50 ppt for Benzene in ambient air. An H2 supply for FID and carrier gas is sufficient, so there is no N2 required.

The Vistachrom® software enables the user to view and store data on an internal computer. It provides comfortable user friendly utilities to recalculate, calibrate and export data and to configure the measurement. The software allows the calculation of retention time, area, mass or concentration profiles in any measuring unit.

Ethernet connectivity provides efficient remote access, allowing the user to download measurement information directly from the instrument without having to be on-site.
