chromaS : H2S, COS, CS2, SO2, RSH

chromaS : H2S, COS, CS2, SO2, RSH Automated online analysis & monitoring of Sulphur Compounds: H2S / COS / CS2 / SO2 / RSH

Chroma S is a fully automatic isothermal gas Chromatograph for the analysis & monitoring of sulphur compounds.

Principle :

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

Features :

  • The double 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

VISTACHROM ® software :
 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
