Analysis of doubly-charged ion reactions and consecutive two-step degradation processes by means of metastable peak mapping

Abstract

Contour maps of metastable peaks are produced by computer-assisted data acquisition and plotted as a function of ion currents of daughter vs. parent ions. Their presentation, evaluation and practical use is demonstrated by analyzing charge separation and other degradation reactions of doubly-charged cations and by identification of sequential reactions in consecutive field-free regions of a double-focusing instrument.
