Flow spectrometry
WebDec 15, 2015 · Where does flow injection analysis mass spectrometry (FIA-MS) stand relative to ambient mass spectrometry (MS) and chromatography-MS? Improvements in FIA-MS methods have resulted in fast-expanding uses of this technique. Key advantages of FIA-MS over chromatography-MS are fast analysis (typical run time <60 s) and method … WebThe mass spectrometer analyzer operates at a high vacuum to facilitate the ions traveling through the analyzer. High vacuum is achieved by use of a fore pump and a turbomolecular pump. For typical conditions (capillary column, 1-2 mL/min flow rate, and an internal diameter of 250-320 µm) the turbomolecular pump can handle the gas flow out of ...
