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 mass spectrometer has a plurality of ion sources for generating a plurality of io n beams. An inlet device for passing ion beams into the mass spectrometer is provided as is a device or mechanism for selecting one of the ion beams for passage through into the mass spectrometer and for blocking the other ion beams. An outlet provides a connection to a mass spectrometer. A correspondi ng method is provided.
