Produce gas-phase ions from sample molecules. This is accomplished in the ion source and, at one time, would normally have required these neutral molecules to be already in the vapor state. New ionization techniques have, however, extended thus process to neutral molecules which are essentially in a solid (condensed) state or in solution.
Separate gas-phase ions according to their mass-to-charge (m/z) ratio. Thus takes place in the analyzer.
Detect and record the separated ions
