Chromatotec Chroma S

Chroma S is a fully automatic isothermal gas Chromatograph for the automated online analysis and monitoring of Sulphur Compounds: H2S / COS / CS2 / SO2 / RSH.

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 linearisation 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
