Analyzer of Sulphurs Compounds and VOC

CHROMATOTEC is specialized in the manufacturing of online gas analysers, monitoring of sulphurs compounds and VOC in Hazardous zones. The system uses proven Gas Chromatography technology, the quality and performance of our systems has been recognised worldwide with recognition from Standard Organisations such as ISO, ASTM and CSA.

The MEDOR® Exp or Exd from CHROMATOTEC® offers continuous, online analysis of sulfur compounds from concentrations as low as 1 ppb in natural and biogas feeds.

Sulfur compounds analysis. Total or speciated compound results. H2S, methyl mercaptan, ethyl mercaptan, THT, TBM, NPM, SBM, IPM, DMS, DMDS are all analyzed by the MEDOR®

ASTM D7493-08 Standard Test Method for Online Measurement of Sulfur Compounds in Natural Gas and Gaseous Fuels by Gas Chromatograph and Electrochemical Detection

Electrochemical detection.  The use of our sulfur specific electochemical cell ensures no interference of results.

Internal calibration system.  All MEDOR® instruments are supplied with internal calibration by permeation tube. Results are thus automatically validated.


The chromEnergy is an industrial gas chromatograph for analysis and monito¬ring of C1C6+ in natural gas and gaseous fuels by TCD detection.

ChromEnergy Exp ATEX Continuous natural gas measurement Automated system for measurements in the range: ppm or % for hazardous area.
