The instrument uses a 6-port valve with a single sorbent trap, and a metallic capillary column.

It has a minimum detection level as low as 15 ppt (for 1,3-Butadiene for e.g.) in ambient air, and analyses up to 32 compounds during a single analysis.

The airmo VOC C2-C6 uses a thermoelectric cooling system to control the temperature of the sample trap when required, for example for the analysis of Ethyne.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 4U (programmed gradient temperature of the oven and pressure/flow control of the carrier gas by the piezo-valve). Before delivery the analyser is tested for one week by our quality control department.

The Vistachrom software enables the user to analyse and store data on a PC. It provides user friendly utilities to recalculate, calibrate, configure the measurement and export data.

The software allows the calculation of retention time, area, mass or concentration profiles.

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…)
