Matrix-assisted laser desorption/ionization mass spectrometry: improved matrix for oligosaccharides.
M D Mohr et al.
Rapid communications in mass spectrometry : RCM, 9(9), 809-814 (1995-01-01)
The aim of this article was to study the influence of different matrix molecules on the quality of matrix-assisted laser desorption/ionization mass spectra of oligosaccharides. An important criterion was the sample preparation, i.e. the crystallization process leading to the matrix
