This paper describes a new scanning mode for quadrupole mass spectrometers. In accordance with the theoretical equations of ion motion in a quadrupolar field, an alternative method of scanning is possible varying only the RF applied to the rods of the quadrupole, keeping constant the amplitude of the AC and DC potentials. First results are reported for a RF scanning range of 0.4–1.1 MHz and an AC amplitude of approximately 250 V. © 1998 John Wiley & Sons, Ltd.
