Pulsed gas introduction into quadrupole ion traps.

W B Emary1, R E Kaiser, H I Kenttämaa, R G Cooks.   

Abstract

Two different Paul-type quadrupole ion traps were equipped with pulsed-valve gas inlets. The duration of a gas pulse inside the trap is variable, and pulses as short as 50 ms (FWHH) have been measured, allowing the use of several gas pulses during one experiment. The benefits of pulsed valves are outlined and demonstrated for chemical ionization experiments and for the use of selective ion-molecule reactions in structure determination of ions and neutral molecules.
