Metrology and on-line Gas Chromatography on sulfur compounds in Natural Gas

Transport natural gas companies require to control qualitatively and quantitatively odorants species in natural gas for safety reasons. Chromatotec has introduced the energyMedor which is automated and on-line analyser designed to measure sulphur compounds in natural gas on site. Proven gas chromatography technique allows for excellent separation of chemical species. A calibration standard check up is included in each analysis to ensure repeatable measurements and good operation. 

In order to improve accuracy and to validate the results permanently, Chromatotec verify continuously the performances of the analyser testing performance criteria on uncertainty, linearity, repeatability …., performing intercalibration, intercomparison in customers laboratories, working on method standardisation with ASTM and comparing results with other gas chromatography analysers (ChromaS FPD detector)

The EnergyMedor’s specific detector is highly sensitive to sulfur compounds, PPM or PPB level at choice. Their unique gas chromatograph conception results in a very clear separation of the compounds, a good stability of the results and a validation of the results with permeation tube. The MEDORs are fully automatic rugged industrial analysers that need very low maintenance.

The intercalibration and intercomparison studies allow to give more and more accuracy to the results obtained in Natural Gas odorisation measurements.
