摘要
An apparatus for electronically controlling a quadrupole in a mass spectrometer, comprises radio frequency (RF) drive circuitry and direct current (DC) drive circuitry coupled to a quadrupole, an RF control loop associated with the RF drive circuitry, a DC control loop associated with the DC drive circuitry, and control loop circuitry associated with the DC control loop, the control loop circuitry configured to alter a response of the DC control loop during a settling time period of a step response such that ion transmission through the quadrupole is greater during the settling time than if the response of the DC control loop during the settling time is unaltered.
