Abstract
A mass spectrometer and method is provided for a time-of-flight analyzer (TOF) having an accelerator stage with a plurality of electrodes to receive and accelerate a plurality of ions, and a drift chamber downstream of the accelerator stage for receiving at least a portion of the accelerated ions. The TOF analyzer also has a pulser coupled to the accelerator stage for applying one or more voltages to the plurality of electrodes and a controller coupled to the pulser to adjust one or more voltages applied to the electrodes to configure the accelerator stage to receive and accelerate positive and negative ions during different cycles of an ion detection period.
