GC5000OS Organic Sulfur Online Chromatography Monitoring System

System Introduction:

The GC 5000 organic sulfur online chromatographic monitoring system was developed, designed, and manufactured by AMA, a German company. The instrument has sub ppt level detection sensitivity and can analyze and test methyl mercaptan, ethyl mercaptan, dimethyl sulfide (methyl sulfide), carbon disulfide, diethyl sulfide (ethyl sulfide), dimethyl disulfide, benzene, and toluene in ambient air. It can also monitor other organic sulfur compounds. The online chromatographic monitoring system has passed EN 14662-3 certification.

The core components mainly include the GC 5000 organic sulfide chromatographic analyzer host and the DIM 200 calibration module.
