Abstract
The effect of the variation of the cation, on the matrix-assisted lase r desorption/ionisation collision induced dissociation (MALDI-CID) spe ctra obtained, has been studied in a hybrid sector-orthogonal accelera tion-time of flight tandem mass spectrometer for some synthetic oligom eric systems. Oligomers of poly(methyl methacrylate) and poly(styrene) in the molecular weight range of approximately 1000-3000 u were analy sed. They were ionised by attachment of various alkali metal and coppe r and silver ions, respectively. The MALDI-CID spectra are shown to va ry with different cations more from precursor ions of lower than those of higher mass-to-charge ratio. (C) 1997 Elsevier Science B.V.
