Abstract
A mass spectrometer system (10) is provided in which the voltage controller (12) can have separate first and second high-voltage control circuits (34, 40) which are physically disconnected from and at different ground planes to one another. Communication between the first and second high-voltage control circuits (34, 40) is enabled via an interface circuit (30) and one or more wireless, preferably radio-frequency, communicators (38, 44, 46, 48).
Claims16
A mass spectrometry system comprising:
- a mass spectrometer having an ion source having a plurality of high-voltage inputs of different voltages;
- a first high-voltage control circuit having a microcontroller and a first high-voltage-circuit wireless communicator, the microcontroller of the first high-voltage control circuit being configured to control a power supply to at least one of the plurality of high-voltage input of the ion source;
- a second high-voltage control circuit having a microcontroller and a second high-voltage-circuit wireless communicator, the microcontroller of the second high-voltage control circuit being configured to control a power supply to at least one of the plurality of high-voltage inputs;
- and
- an interface circuit comprising a wireless communication means, and a microcontroller which is in communication with the wireless communication means;
- wherein the first and second high-voltage control circuits are physically spaced apart from and are at different ground planes to one another, the interface circuit providing communication therebetween by communication between the wireless communication means and the first and second high-voltage wireless communicators.
