Electrospray ionization and multi-stage mass spectrometry (ESI-MSn) combine the analytical techniques of ESI and MSn. ESI-MSn is widely used in the field of bioanalysis and especially plays an important role in the analysis of the structure and composition of biomolecules, such as glycans, proteins, and nucleic acids. ESI is a type of ionization technique, which is used to convert molecules in solution into charged ions by spraying them with an ESI ion source under a high voltage to convert molecules in solution into charged ions. The ESI ion source uses a needle or capillary to eject high-speed droplets to form a microscopic electrospray in which molecules in solution are ionized and charged. MSn refers to multistage mass spectrometry (MS), which involves acquiring MS data from complex samples in a mass spectrometer by continuously performing multiple tandem MS scans. ESI-MSn combines an ESI ion source and multistage MS to provide more detailed and comprehensive mass spectral data.
ESI-MSn enables high-throughput glycan screening and rapid analysis of glycan structures and modifications in a large number of samples. This is extremely useful for glycomics research, metabolomics, and drug screening of glycans in drug discovery and development.
