Sodium salts effect on the time of flight mass spectra of some amino acids in the direct‐laser desorption ionization and matrix‐assisted laser desorption/ionization
Abstract:One of the problems in the matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF MS) of small molecules is the overlap between the peaks originated from the matrix and analyte. The MALDI and the direct laser desorption ionization (direct-LDI) spectrum of the phenylalanine amino acid (FAA) has been recorded and assigned in the absence and presence of the salts, including NaF and NaOH. It was seen that the peaks originated from the matrix were suppressed in the MALDI spectrum of… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
