WebThe three essential functions of a mass spectrometer, and the associated components, are: 1. A small sample is ionized, usually to cations by loss of an electron. The Ion Source 2. The ions are sorted and separated according to their mass and charge. The Mass Analyzer 3. The separated ions are then measured, and the results displayed on a chart. WebA mass spectrometer produces charged particles (ions) from the chemical substances that are to be analyzed. The electric charge is like a “handle” that allows the electric and magnetic fields to move the charged particles around so that we can measure the mass ("weight") 1 of the charged particles. react get component name
