Abstract
An ion guide or ion trap that comprises a plurality of electrodes (102) is disclosed. The ion guide or ion trap includes a detector (205) that can detect light or particles (114) emitted from the ion guide or ion trap due to electrical breakdown, and a control circuit (111) that can control the ion guide or ion trap in response to the detector (205) detecting light or particles (114) emitted from the ion guide or ion trap.
Claims20
An ion guide and/or trap comprising:
- a plurality of electrodes;
- a detector configured to detect light or particles emitted from the ion guide and/or ion trap due to electrical breakdown;
- and
- a control circuit configured to control the ion guide and/or ion trap in response to the detector detecting light or particles emitted from the ion guide and/or ion trap.
An ion guide and/or trap comprising:
- a plurality of electrodes;
- one or more voltage sources configured to apply one or more voltages to the plurality of electrodes;
- a detector configured to detect light in the vicinity of the electrodes;
- and
- a control circuit configured to reduce, remove or turn off one or more of the one or more voltages in response to the detector detecting light in the vicinity of the electrodes.
A method of operating an ion guide and/or trap comprising a plurality of electrodes, the method comprising:
- detecting light or particles emitted from the ion guide and/or ion trap due to electrical breakdown;
- and
- controlling the ion guide and/or trap in response to detecting light or particles emitted from the ion guide due and/or ion trap to electrical breakdown.
