Electrospray Ionization
A procedure used in mass spectrometry analysis. Means of delivering nonvolatile analytes into the gas phase for mass analysis. Best used on molecules which are charged in solution or readily accept a charge. Particularly well suited to the analysis of biomolecules. Can be used to probe tertiary structure and non-covalent interactions (from NCSU Mass Spectrometry Facility web site)
