  • Publication number: 20190080892
    Abstract: A voltage supply system for supplying an RF voltage to an RF resonant load comprising an ion-optical component of a mass spectrometer is disclosed. The system comprises a Direct Digital Synthesiser (“DDS”) arranged and adapted to output an RF voltage. The voltage supply system is arranged and adapted: (i) to vary the frequency of the RF voltage output by the Direct Digital Synthesiser, (ii) to determine a first resonant frequency of the RF resonant load comprising the ion-optical component, and (iii) to determine whether or not the generation of an RF voltage at the first resonant frequency by the Direct Digital Synthesiser would also result in the generation of a spur frequency close to the first resonant frequency.

  • Patent number: 9786481
    Abstract: A mass spectrometer or ion mobility spectrometer is disclosed comprising means for detecting a blockage in an inlet orifice arranged between an ion source and a vacuum chamber. The blockage is detected as a result of a reduction in pressure within the vacuum chamber. This change in pressure is detected indirectly by monitoring the amount of power that a vacuum pump is using, the amount of current that a vacuum pump is drawing, the temperature of a vacuum pump or a region in proximity to the vacuum pump, or the flow rate of gas out of a vacuum pump.
