Basics of LC/MS (5968-2543E)
www.agilent.comLiquid chromatography uses high pressure to separate a liquid phase and produces a high gas load. Mass spectrometry requires a vacuum and a limited gas load. For example, common flow from an LC is 1 ml/min of liquid which, when converted to the gas phase, is 1 l/min. However, a typical mass spectrometer can accept only about 1 ml/min of gas ...
