Figure 6: Schematic diagram of a quadrupole mass spectrometer. The pairs of opposing electrodes are electrically connected to a balanced voltage source having a radio frequency component superimposed on a constant potential. Combinations of values for the amplitude and frequency exist that allow ions of a given mass from a beam of constant energy to emerge undeflected.
