Basics of LC/MS (5968-2543E) - Agilent

Interfacing LC and MS There has been a major focus on improving the interface between the LC and the MS. Liquid 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
