A GC/PID for automatic monitoring of BTEX in air, water and soils

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 application Benzene or 1,3-Butadiene 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.

MCERTS certified analyser for benzene measurement following EN 14662-3 norms
 
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 a industrial 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.
LCD DISPLAY
Results output : different communication protocols available
 

For 40 years, Chromatotec, alliance of the expertise of three companies, Chromato-Sud, airmotec, Medor, is specialized in the manufacturing and sales of online gas analysers by chromatography.

Worldwide known for its leading-edge of technology, our group proposes gas analysis systems with in-built computers and its own developed software, Vistachrom, to pilot these process analyzer.

We manufacture several analyser ranges which mounted in 19" rack and 4U height with everything included in the instrument. Our main GC 866 ranges are :
* MEDOR range : analysis of sulphur compounds in natural gas (gas company) and ambient air (waste water plant application) since 1975
* AIRMO range : analysis of VOC / BTEX in ambient air (ppb, ppt, ppm)
* CHROMA range : analysis of impurities in pure gas and in industrial air (ppb / %). This range has been developed since the creation of Chromato-Sud company in 1986.
* DET range : Specific detectors.

Chromatotec supplies complete cabinets with complementary instruments, in-built computer and appropriate accessories into a cabinet with air conditionning in option for accurate and complete compounds detection.

Chromatotec proposes you global solutions with integration of automation systems (multiplexer, peripheral equipment, alarms, communication protocols…)
