Overview
Gas chromatograph mass spectrometer LGCMS-101 system has a pre-filter mass analyzer and an electron multiplier to provide excellent sensitivity. Desorption for solids is carried out with a flow rate of 1 to 1.5 ml/min at a regulated temperature between 100 and 350℃. The analysis is sensitive and focused, with a seven-stage temperature programming and an interface temperature of 450℃.
