Surface-induced dissociation by Fourier transform mass spectrometry

Abstract
A detailed procedure for performing surface-induced dissociation (SID) of ions in a dual-cell Fourier transform mass spectrometer is described. It is shown that the technique is applicable to both laser desorption measurements. SID spectra of perfluorortri-n-butylamine, anthracene, (5,10,15,20-tetraphenyl-21H,23H-porphinato)-iron(III) chloride, and [5,10,15,20-tetrakis(2,6-dibromophenyl)-21H,23H-porphinato]iron(III) chloride are presented. Conversion efficiencies of molecular ions between 1% and 30% are obtained. It is concluded the method holds promise for dissociation of high mass laser-desorbed ions.
