The effects of methanol, ethanol, propan-2-01 and acetonitrile on the aerosol matrix-assisted laser desorptionlionization (MALDI) ion signal of hradykinin, bovine insulin and myoglobin were examined. The effect of these solvents mixed with water was also studied. The aerosol MALDI ion signal for eac

Quantitative aspects of oligonucleotide analysis by matrix-assisted laser desorption/iotion (MALDI) mass spectrometry remain largely unexplored relative to the efforts that have been devoted to quantitative peptide and protein analysis. The successful quantitation of these other biopolymers coupled
## Matrix -assisted laser desorption/ionization (MALDI) mass spectrometry (MS) of oligosaccharides and polysaccharides has been investigated in detail. It is demonstrated that cationized species of oligosaccharides, [MNa] and [MK] , are dominant products under the MALDI condition, and negative ion
## Abstract Cysteine sulfonic acidβcontaining peptides, being typical acidic peptides, exhibit low response in matrixβassisted laser desorption/ionization (MALDI) mass spectrometry. In this study, matrix conditions and the effect of diammonium hydrogencitrate (DAHC) as additive were investigated fo
