Lipid Analysis by Direct Ionization Mass Spectrometry DART-MS

Abstract

Gas chromatograph (GC), liquid chromatograph (LC), liquid chromatograph/mass spectrometry (LC/MS) are widely used for analyzing useful ingredients in food samples such as lipids. Generally, samples are pretreated according to the analytes, such as deproteinization and derivatization, and are used for analysis. In recent years, direct ionizations and ambient ionizations have been actively studied as an ionization method for mass spectrometry. In DART-MS analysis using DART (Direct Analysis in Real Time) which is a type of the direct ionizations, food samples can be analyzed with little or no sample pretreatment. In this paper, we introduce applications of various lipid analyzes by mass spectrometry using DART-MS.
