Application Used as a matrix for MALDI-TOF mass spec. Good matrix for ionization of peptides, proteins and carbohydrates. Good for reflectron mass spec.
Application Most commonly used matrix for carbohydrates. For MALDI-MS of free neutral glycans. Produces [M+Na]+ ion; may show a weaker [M+K]+ ion. Other species may be generated by the addition of the appropriate inorganic salt.1 Protocols & Applications Methods of glycosylated protein analysis by Mass Spectrometry
