LC/ESI-MS analysis of underivatized amino acids and mass spectrum [PDF]

open access: yesarXiv, 2016
We report the method of LC/ESI-MS analysis of underivatized amino acids with corresponding mass spectrum and fragmentation patterns. Diagnostic product ions determined by mass spectrometry can support the qualitative identification and quantitative estimation of individual amino acids. Therefore, the optimization of chromatographic separation using the
