In this experiment students learn how to operate a mass spectrometer and the vacuum system associated with it. Students plot a spectrum of the near-vacuum in the chamber, and investigate the ionization process for two different pure gases. There have been six Nobel Prize winners for work in the development of Mass Spectrometry, the most recent (Chemistry 2002) being for ionization methods for biological macromolecules.
(The experiment is currently located in MP226; last write-up revision: Feb. 2005.)
