How Does a Mass Spectrometer Work?
5.1 Introduction
Mass spectrometers can be divided into three fundamental parts, namely the ionisation source, the analyser, and the detector (“Ionization Methods in Organic Mass Spectrometry”, Alison E. Ashcroft, The Royal Society of Chemistry, UK, 1997; and references cited therein).
The sample under investigation has to be introduced into the ionisation source of the instrument. Once inside the ionisation source the sample molecules are ionised, because ions are easier to manipulate …

The m/z values of the ions are plotted against their intensities to show the number of components in the sample, the molecular weight of each component, and the relative abundance of the various components in the sample.
The type of detector is supplied to suit the type of analyser; the more common ones are the photomultiplier, the electron multiplier and the micro-channel plate detectors.
