Title: Massive cluster impact ionization of saccharides

Abstract

The authors studied the utility of ionizing saccharides by massive cluster impact (MCI), a form of secondary ionization wherein the primary ions are high molecular weight clusters. For a number of compounds and classes, MCI yields copious secondary ions without prior derivitization or the need to find a suitable matrix. In fact, MCI can be used for in situ ionization of some analytes directly from biologic tissue. For the simple sugars and disaccharides that were studied, the authors found that persistent ( e.g. > 2 h) positive and negative secondary ion emission could almost always be detected from pure samples. The authors characterized the secondary anions from a variety of saccharides by tandem mass spectrometry (MS/MS), and found the behavior of the MS/MS spectra to be consistent, sensible, diagnostic and invariant with the dose suffered by the sample.
