MASS SPECTROMETRY RESOURCE

Theory Section



In this section of the web site you will find a detailed description of the basic and advanced theories of mass spectrometry. This will cover the various common place methods of sample ionisation and mass measurement as well as details of ion detection, hyphenated techniques, multiple sector/multistage mass analysis (tandem and sequential mass spectrometry) and some basic ideas about ion fragmentation chemistry. More details can also be found on the relevant research pages.
