It filters the ion for the desired m/z ratios to allow the detector to output the mass spectrum [1-2]. Beside filtering m/z ratio, they also can act as an ion storage center, fragmentation chamber or even an ion ejection compartment [1-2].

A Mass Spectrometer is an instrument which electrically analyzes the mass of a sample molecule. Therefore, molecules need to be ionized. A sample flowing from a GC is ionized in the ion source. There are various ionization methods. Explanation of the ion source here will be based on the most typical ionization method, EI.
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.
