Abstract
An amplifier arrangement can provide a varying electrode voltage to an ion optical device. The amplifier arrangement comprises: a high-speed amplifier, configured to receive an input to the amplifier arrangement and provide a low voltage output; and a low-speed controllable voltage source, arranged to float on the low voltage output and configured to provide a high voltage output of the amplifier arrangement. The high voltage output of the amplifier arrangement is fed back for control of the high-speed amplifier. The amplifier arrangement beneficially forms part of a power supply for supplying the varying electrode voltage, for example as part of an ion analytical system.
