Chromatec AirTOXIC BTX PID is a GC/PID for automatic monitoring of
BTEX in air, water and soils. The instrument uses gas chromatography, to
measure the amount of Benzene, Toluene, Ethylbenzene and Xylenes in the
air from sub-ppb levels up to 1,000 ppb.
The main features of the airTOXIC BTX PID are its
sensitivity, compact size, mobility and flexibility. Everything from the
sample port to the data storage is integrated in a 19″-rack 5U.
The airTOXIC BTX PID uses a port valve with a single absorbent trap
and a metallic 0.28mm ID column. It has a programmed gradient
temperature of the oven and pressure/flow control of the carrier gas.
Detection is done using a Photo-Ionisation Detector with a self-cleaning
10.6 eV PID lamp for high stability.
Its minimum detection limit is as low as 10 ppt for Benzene or 1.3-Butadiene (A76022) in ambient air.
Vistachrom® Software
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.
