Gas Chromatograph and Mass Spectrometry (GCMS), Model GC-MS-II, DRAWELL (CAT#: STEM-C-0009-CJ)

GCMS (Gas Chromatography and Mass Spectrometry) is an integrated device of GC and MS, a precise analytical instrument for detecting what (qualitative) and how many (quantitative) compounds are. GC separates the vaporized samples into the chromatographic column, and the separated compounds enter the MS for detection. It can be widely used in environmental protection, food safety, electronics industry, flavor and fragrance industry, textile industry, petrochemical industry, pharmaceutical industry, judicial appraisal, and other fields.
