Gas chromatography mass spectrometry GC-MS-879


Gas chromatography mass spectrometry GC-MS is a high precision Gas chromatograph mass spectrometer with pre-filter mass analyzer and electron multiplier ensuring high sensitivity. Desorption for solids is performed at controlled temperature between 100 ~ 350 °C with a flow rate of 1 to 1.5 ml / min. With seven stage temperature programming and an interface temperature of 450 °C the analysis is sensitive and specific.
