What is a Mass Spectrometer and How Does it Work? Excedr

WebFeb 19, 2016 · One way to do it is to use a mass spectrometer. A variation of this was done in World War II, to separate Uranium isotopes. You can separate them because they have different masses. Uranium-238 has more neutrons than Uranium-235. Therefore, it has more mass. Let's see how my mass spectrometer works. The first step is ionization. WebMass spectrometry, the science and technology of gaseous ions (1), has as its basis the measurement of mass-to-charge ratios (m/z) of ions. All atomic and molecular ions are, in principle, accessible by mass spectrometry, making it a universal method for chemical analysis. Its implementation requires suitable methods of ion generation, ion
