APPARATUS FOR EFFICIENT LIQUID CHROMATOGRAPHY/MASS SPECTROMETRY PROCESSING

摘要

A chromatographic apparatus includes at least one sample preparation stage with a plurality of individually mounted separation columns, that can have a common pressurizable header at the column input side for parallel sample preparation. The column output side can be releasably connected to a mass spectrometer input operating, for example, with ESI. The sample preparation stage is moveable in at least one direction for sequential processing of the columns by the mass spectrometer. Sample preparation and analysis can be automatically controlled.
