Chromatotec has engineered and manufactured the new Medor Exd designed to operate in hazardous area environment zone 1 without any purging system

Description  :

The MEDOR Exd is an automatic and isothermal gas chromatograph dedicated to sulfur compounds analysis (H₂S, mercaptans and sulphides) in different matrices.
Two versions exist :

• the MEDOR Exd ppm which measures at ppm levels
• the MEDOR Exd ppb which measures at ppb levels.

Principle  :

• Hazardous area Ex d enclosure 
• Internal temperature and pressure monitoring
• Loop injection by automatic valve
• Detection is made by a gas-liquid reaction
• Sulfur specific detector – no interferencees
• The detector life is in excess of 10 years

Features  :

• ASTM D7493-08 : Standard Test Method for Online Measurement of Sulfur Compounds in Natural Gas and gaseous Fuels
• Fully automatic, continuous online analyzer in an Ex enclosure
• Integrated industrial computer
• Storage of date & time stamped chromatograms

VISTACHROM ® software 
 Chromatotec developed software system enables :

• Remote monitoring & injection control
• Full traceability with on board archiving of results
• QC Set up and control of threshold alarms
• Export of data MODBUS / MGS1 / 4-20mA / 0-10V

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…)
