Abstract: A mass spectrometer comprising: a vacuum chamber; and an ion inlet assembly for transmitting analyte ions into the vacuum chamber; wherein the spectrometer is configured to operate in a cooling mode in which it selectively controls one or more gas flow to the ion inlet assembly for actively cooling the ion inlet assembly.

Abstract: A mass spectrometer is disclosed comprising an ion optics device housing having one or more external electrical connectors (1719) provided thereon. An ion optics device (301) is arranged inside the ion optics device housing, the ion optics device (301) comprising one or more electrodes for manipulating ions, the one or more electrodes being electrically connected to the one or more external electrical connectors (1719) provided on the ion optics device housing. A voltage supply housing (1717) is provided having one or more external electrical connectors provided thereon. One or more voltage supplies are arranged inside the voltage supply housing (1717), the one or more voltage supplies being in electrical communication with the one or more external electrical connectors provided on the voltage supply housing.

Abstract: A mass spectrometer includes a control system arranged to assess an operational state of the mass spectrometer. When a fault is detected, the control system assigns the fault to one of a plurality of categories, including a first category of faults which may be attempted to be rectified automatically by the mass spectrometer, a second category of faults which may be attempted to be rectified by the user, and a third category of faults which may only be attempted to be rectified by a service engineer. When a fault is assigned to the first category of faults, the control system initiates an attempt to automatically rectify the fault. When a fault is assigned to the second category of faults, the control system causes information relating to the fault to be displayed to the user, including data indicative of the fault and data one or more steps to be taken by the user to attempt to rectify the fault (2000).

Abstract: A mass spectrometer is disclosed comprising a system control module (1715) for controlling the operation of the mass spectrometer. The system control module (1715) comprises one or more functional modules, each functional module being operable to perform a predetermined function of the mass spectrometer. The system control module (1715) and/or one or more functional modules are operable to communicate non-time information with each other using a time code of a communications protocol.
