chromatograph

GC-902 series gas phasechromatographPractical gas phase configuration for single detectorchromatographThe instrument can be equipped with hydrogen flame ionization detector (FID), thermal conductivity cell detector (TCD), electron capture detector (ECD), etc. The instrument is equipped with an intelligent rear door, which can perform constant temperature and 9-level programmed heating operations. The instrument adopts a color touch screen operation interface, which is convenient and intuitive to operate. It has a compact structure, beautiful appearance, good reliability, and high cost-effectiveness. It can be widely used in production and research departments in industries such as petrochemicals, pesticides, environmental protection, and food inspection.
