A new method of selective ion storage in a quadrupole ion trap is described. Broadband waveforms were applied to the endcaps of an ion trap to eject unwanted ions by resonance excitation, which enhanced the storage of selected target ions. A unique trapping field amplitude modulation technique allow

The competition between ion dissociation and ion ejection during resonant excitation in a quadrupole ion trap is investigated. Ions of similar mass but with a range of critical energies for the onset of dissociation have been examined. The effects of the amplitude and duration of the resonant excita
The analysis of a targeted group of nucleoside antibiotics has been accomplished through the use of selective ion-molecule reactions and collision-activated dissociation (CAD) techniques in a quadrupole ion trap. A series of homologous ether reagent ions generated from dimethyl ether, di-n-butyl eth
Investigations on ion injection into a laboratory-built quadrupole/ion trap tandem instrument (Nermag R10-10/ITMS Finnigan) with a 90Γ geometry are described. The quadrupole dual electron impact/chemical ionization (EI/CI) source was used as an external source to prepare ions under EI (or CI) condit
