Abstract : A mass spectrometer is disclosed having a detector that detects the induction of a charge as an ion pulse passes by the detector and provides a representative output signal thereof. The inductive detector output signal is present regardless of the presence or intensity of preceding ion pulses and also the inductive detector is relatively insensitive to the velocity of the charged particles being detected. Further, the inductive detector does not destroy the vast majority of the ion pulses that it detects so that the non- destroyed ion pulses may be further analyzed by spectrometers attached in tandem.
