Mass Spectrometry

Mr. Andersen's Chemistry Essentials video 9 covers mass spectrometry, a technique for separating atoms, isotopes, and molecular fragments by mass. The video begins with a discussion of John Dalton's atomic theory and its historical significance. It then explains how mass spectrometry identifies isotopes, calculates average atomic mass, and analyzes samples. The video details the components of a mass spectrometer, including the ionizer, mass analyzer, and detector, and demonstrates the calibration process. An example using chlorine isotopes illustrates the technique's application. The video concludes with a discussion of mass spectrometry's broader applications in chemistry.
