2137137 9422565 PCTABS00033 Improved methods of using an ion trap mass spectrometer (10) whereby AC voltages supplemental to the AC trapping voltage are used for scanning the trap, for conducting chemical ionization experiments, and for conducting MS experiments, are shown. In one embodiment a broadband supplemental AC voltage is applied to rid the trap of ions above or below a preselected cutoff mass. This is particularly useful in conducting chemical ionization (CI) experiments for eliminating high mass sample ions that are formed when the reagent gas is ionized by electron impact ionization (EI). Likewise, this technique may be used to eliminate low mass reagent ions when conducting an electron impact ionization experiment in the presence of a reagent gas.
