Abstract: A computerized control system for a plurality of mass spectrometers, wherein voltage ranges corresponding to predetermined ions are selected and programmed into the computer. Instead of the usual scan, the computer drives a power supply to move from range to range, and to vary the voltage incrementally within each range to accurately define the peaks of interest. The voltage delivered at the spectrometer is fed back to the computer to serve as a check on the power supply and the overall system.
