Time-Resolved Magnetic Dispersion Mass Spectrometry: A Technique for Multidimensional Analysis.

Abstract

A new type of multidimensional mass spectrometer is presented. Utilization of ion beam pulsing and time-resolved detection techniques in a magnetic sector mass spectrometer allows simultaneous momentum and velocity analysis of the ions. This combination of factors provides parent ion and daughter ion mass assignments that are independent of ion energy. Parent, daughter, and neutral loss spectra can be obtained as in current MS/MS instruments. Equations for mass determination are given, various scanning modes are described, and the expected resolution and sensitivity are evaluated. Demonstration data are presented for daughter ions of a selected metastable decomposition. The potential for the technique in analytical applications is considered, particularly in light of a proposed high-speed data acquisition system. (Author)
