Method and device for interfacing liquid chromatography or supercritical fluid chromatography with a mass spectrometer (LC-SFC/MS)

摘要

A method for interfacing LC or SFC chromatographic equipment with a mass spectrometer, comprises the steps of: positioning at least one conductive element (2) adjacent said column end (1); positioning said column end (1) and said conductive element (2) at a preselected distance from the mass spectrometer ion source (11); and connecting said conductive element (2) to a high voltage source and grounding said ion source, or viceversa.
