airmoModel S -Automatic Isothermal Gas Chromatograph Analyzer

SHARE

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.
