Abstract

A new external ionization source for matrix-assisted laser desorption/ionization (MALDI) Fourier transform mass spectrometry is described. This design allows a number of samples to be introduced simultaneously. This capability is important for studying metal ion-coordinated species produced by MALDI. The source is used to observe the effects of alkali metal ion affinities of neutral oligosaccharides on the intensity of the respective quasimolecular ions.
