Abstract
Control of an amplitude of a signal applied to rods of a quadrupole is described. In one aspect, a mass spectrometer includes an amplifier circuit that causes a radio frequency (RF) signal to be applied to the rods of the quadrupole. A controller circuit can determine that the actual amplitude of the RF signal differs than the expected amplitude and, in response, identify current and past environmental and performance parameters to adjust the amplitude.
