ABSTRACT:
A power supply system for a quadrupole mass spectrometer includes an RF (radio frequency) power source for generating RF voltages and a voltage divider functioning as a DC (direct current) voltage generating circuit. This voltage divider divides the RF voltages and then rectifies them so as to derive DC voltages while maintaining a proportional relationship to the RF voltages. Thereafter, the DC voltages are superimposed on the RF voltages. The resultant voltages are applied to the electrodes of the quadrupole mass spectrometer.
