mercaptans and sulphides in ambient air

An autoGC-trap-FPD for low sulfur quantification

airmo S is a fully automatic isothermal gas Chromatograph for the ana­lysis & monitoring of sulfur compounds with Sulfur Specific Detector.

This solution is specific for application where low sensitivity on sulfurs must be reached. This auto GC uses a valve with 1 sample trap, and metallic capillary columns.

The main specifications are :

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