AirTOXIC BTX PID

Principle

This instrument uses a port valve with a single absorbent trap, and a 30 meter metallic 0.28 mm ID column.

Minimum detection level as low as 10 ppt for Benzene or 1,3-Butadiene (A76022) in ambient air.

Miniaturization, sensitivity, mobility and flexibility are its main features. Everything from the sample port up to the data storage is integrated in a 19″-rack 5U.

Programmed gradient temperature up to 202°C for the column oven and pressure/flow control of the carrier gas .

Linearity on area with R2 > 0.995

European range: 0.45 to 45 µg/m3 = 0.1 to 14.5 ppb.

Before delivery the analyser is tested for one week by our quality control department.

Photo ionisation detector (PID), 10,6 eV lamp.

Self-cleaning of the lamp ensures high stability.

Bi-directionnal RS-232 C to transfer data and results to the internal computer.

Vistachrom software enables the user to view and store data on an industrial computer. It provides 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.
