PARALLEL SAMPLE INTRODUCTION ELECTROSPRAY MASS SPECTROMETER WITH ELECTRONIC INDEXING THROUGH MULTIPLE ION ENTRANCE ORIFICES

摘要

An interface apparatus, for coupling a plurality of ion sources to a massspectrometer has a plurality of ion sourcesfor generating a plurality of ion beams. An inlet device for passing ion beamsinto the mass spectrometer is provided as is a device ormechanism for selecting one of the ion beams for passage through into the massspectrometer and for blocking the other ion beams.An outlet provides a connection to a mass spectrometer. A corresponding methodis provided.
