摘要：
The invention relates to methods and devices for the effective capturing of externally generated ions in an RF operated quadrupole ion trap. The invention involves applying a voltage consisting of positive and negative pulses, instead of a sinusoidal RF voltage, during the capturing process, with capturing intervals between each pulse in which the voltage is low.
