Mass Spectrometry

009 - Mass Spectrometry In this video Paul Andersen explains how a spectrometer was used to identify the presence of isotopes. This modified Dalton's original atomic theory because atoms of the same element had different masses. The functional parts of a mass spectrometer are detailed including the ionizer, mass analyzer and the detector. A simulation of Chlorine isotopes along with an average atomic mass calculation is included. Music Attribution Title: String Theory Artist: Herman Jolly http://sunsetvalley.bandcamp.com/trac...
