Abstract
An interface apparatus, for coupling a plurality of ion source to a mass spectrometer has a plurality of ion sources for generating a plurality of ion 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 corresponding method is provided.
Claims18
An interface apparatus, for coupling a plurality of ion sources to a mass spectrometer, the apparatus comprising:
- a plurality of ion sources for generating a plurality of ion beams;
- inlet means for passing the ion beams into the mass spectrometer;
- selection means for selecting one of the ion beams for passage through into the mass spectrometer and for blocking the other ion beams;
- and
- an outlet for connection to a mass spectrometer.
A method of analyzing a plurality of samples, the method comprising the steps of:
- (1) passing the plurality of samples through a plurality of ion sources, to generate a plurality of ion beams;
- (2) passing the ion beams through an inlet means, having an outlet for connection to a mass spectrometer;
- (3) selecting one ion beam for passage through to the outlet;
- (4) within the inlet means, permitting passage of said one selected ion beam through to the outlet, and blocking passage of the other ion beams.
