A process for the excitation of the oscillations of the ions in ion traps with frequencies

摘要

the invention concerns a procedure for simultaneous excitation of the oscillations of ions resonanten various mass to charge ratios in ionenfallen, particularly for the ejection of unwanted types of ions promote corrosion, by building hochfrequenzspannungen with different frequenzkomponent at the ionenfalle electrodes.$a the invention is to provide a broadband signal for a period of time to produce and store the minimum possible duration so that the ionenfalle successive cycles can be used to phasenspru00fcnge without unwanted disturbances. the excitation of the ions in the time period and time as constant as possible.the duration of the zeitperiodes is the necessary massenauflu00f6sung. the excitation is terminated by the broadband signal in a constant function is zero is controlled.
