Chroma S

Sulfur compounds analysis: H2S / COS / CS2 / SO2 / RSH by Chroma S. Automated online analysis & monitoring of Sulfur Compounds: H2S / COS / CS2 / SO2 / RSH. Chroma S is a fully automatic isothermal gas Chromatograph for the analysis & monitoring of sulfur compounds.


  • Continuous, uninterrupted sampling.
  • Sample is injected into column for separation.
  • Controlled oven selects optimum temperature based on application detection achieved by a sulfur specific photometric dual flame detector.


  • The dual flame ensures no quenching occurs
  • Automatic linearization of compounds
  • Identification of compounds is based on their retention time (Elution from the column)
  • Automatic data validation as standard with the internal permeation tube


Chromatotec developed software system allows:

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