Oligosaccharide Analysis via Anion Attachment Using Negative Mode Electrospray (ES) and Matrix Assisted Laser Desorption/Ionization (MALDI) Mass Spectrometry
Eleven tested anions were able to form adducts with neutral oligosaccharides at low cone voltage in negative ion mode electrospray mass spectrometry. Among them, fluoride and acetate have the abilities to significantly enhance the absolute abundance of [M-H]- for neutral oliogosaccharides. The …

Characterization of Oligosaccharides and Nanoparticles by MALDI-TOF Mass Spectrometry
… by negative ion mode MALDI using anion attachment followed by PSD are investigated. By careful initial adjustment of the focusing mirror ratios allowing acquisition of the peaks of interest within the same PSD segment, it is possible to obtain highly reproducible relative ion …
