ABSTRACT:
A mass spectrometer is disclosed which yields fast, full-scan spectra over a wide mass-to-charge ratio range. The instrument contains an ion source which generates nearly monoenergetically-pulsed ion packets which spatially focus at a predetermined distance along the drift path of the ions, a mass filter/analyzer which linearly disperses or deflects the ions in the ion-packets by mass-to-charge ratio by applying a traverse, quadratically time-varying and increasing electric field over the entire length of the deflection region of the mass filter/analyzer, and a spatial mass detector. A method of analyzing the mass-to-charge ratio of ions is also disclosed.
