H2S, mercaptans, THT, sulphides, total sulfur and odor measurement

Online analysis and monitoring of sulfur compounds in natural gas

Description :

The energyMEDOR is an automatic and isothermal gas
chromatograph dedicated to sulfur compounds analysis (H2S, mercaptans and sulphides) in different matrices.
Two versions exist : the energyMEDOR ppm which measures at ppm levels and the energyMEDOR ppb which measures at ppb levels.

Principle :

  • Loop injection by automatic valve
  • Detection is made by a gas-liquid reaction
  • Sulfur specific detector – no interferences
  • The detector life is in excess of 10 years

Features :

  • Online, continuous sampling
  • No interference from other compounds
  • Low maintenance instrument – detector life may be up to 10 years
  • Automatic Validation of results by Internal Permeation Tube
  • Modifiable threshold alarms – High / Low alarm for odorising processes

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
