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). When a fault is assigned to the third 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 an indication that the user should call a service engineer.

First claim

The invention claimed is:

1. A mass spectrometer comprising a control system arranged to assess an operational state of the mass spectrometer, wherein, when a fault is detected by the control system, the control system is arranged to assign the fault to one of a plurality of categories, wherein the categories include 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, the control system performing one or more steps based upon the assigned category of the fault;
wherein, when a fault is assigned to the second category of faults, the control system is arranged to cause information relating to the fault to be displayed to the user, the information comprising data indicative of the fault and data indicative of one or more steps to be taken by the user to attempt to rectify the fault; and
wherein the control system is arranged, when it is determined that a fault has not been rectified after a permitted number of attempts by a user, to reassign the fault to the third category of faults which may only be attempted to be rectified by a service engineer.

2. The mass spectrometer of claim 1 , wherein when a fault is assigned to the first category of faults, the control system is arranged to proceed to initiate an attempt to automatically rectify the fault.

3. The mass spectrometer of claim 1 , wherein when a fault is assigned to the third category of faults, the control system is arranged to cause information relating to the fault to be displayed to the user, the information comprising data indicative of the fault, and an indication that the user should call a service engineer.

4. The mass spectrometer of claim 1 , wherein the control system is arranged to assess the operation of one or more parts of the spectrometer, and assign a status to the or each part from a list of possible statuses, wherein the possible statuses which may be assigned to the or each part include one or more fault state, and one or more non-fault state.

5. The mass spectrometer of claim 1 , wherein the control system assigns detected faults to a category based on a severity of the fault.

6. A mass spectrometer comprising a control system arranged to assess an operational state of the mass spectrometer, wherein the control system is arranged, when a fault is detected, to determine whether the fault is in a category of faults which may be attempted to be rectified by a user, and when the fault is in such a category, the control system is arranged to cause information relating to the fault to be displayed to the user, the information comprising data indicative of the fault and data indicative of one or more steps to be taken by the user to attempt to rectify the fault; and
wherein the control system is arranged, when it is determined that a fault has not been rectified after a permitted number of attempts by a user, to reassign the fault to a category of faults which may only be attempted to be rectified by a service engineer.

7. The mass spectrometer of claim 6 , comprising where multiple faults which may be attempted to be rectified by a user exist simultaneously, using priority levels associated with the faults to determine an order in which the faults are to be presented to a user.

8. The mass spectrometer of claim 6 , wherein the data indicative of the one or more steps to be taken comprises one or more image and/or one or more instructional video.

9. The mass spectrometer of claim 6 , wherein the control system is arranged to perform one or more tests to determine whether the fault has been rectified once the user has attempted to rectify a fault.

10. The mass spectrometer of claim 6 , wherein the control system is arranged to display one or more graphical elements to a user which may be used by the user to provide an indication that they have attempted to rectify the fault.

11. The mass spectrometer of claim 6 , wherein the displayed data indicative of a fault is associated with a colour indicative of the category of the fault.
