The ability to analyse polar, nonvolatile biological molecules was realised with the introduction of "soft" ionisation techniques such as fast atombombardment (FAB/MS), thermospray (TSI/MS), and most recently and importantly, electrospray ionisation (ESI/MS) which allows liquid chromatography to interface with mass spectrometry.
