Multi-pressure stage mass spectrometer and methods
A mass spectrometer includes a plurality of guide stages for guiding ions between an ion source and an ion detector along a guide axis. Each of the guide stages is contained within one of a plurality of adjacent chambers. Pressure in each of the plurality of chambers is reduced downstream along the guide axis to guide ions along the axis. Each guide stage may further include a plurality of guide rods for producing a containment filed for containing ions about the guide axis, as they are guided to the detector.
