Maintenance Of The Focus Electrodes - Shimadzu IonFocus Instruction Manual

5 Maintenance

5.2.4 Maintenance of the Focus Electrodes

The focus electrodes transport ions into the mass spectrometer. They become soiled over
long periods of use, which decreases transport efficiency and detection sensitivity. When
this happens, clean the parts of the focus electrodes.

Be sure to adjust the projection length of the ESI capillary to 0 mm or less.
If the ESI capillary projects at all, the tip of the capillary may stick into your
fingers during the work.
Contact with fingers may also reduce sensitivity.
The inside of the ionization unit reaches a high temperature. Wait until the
temperature decreases sufficiently before handling or servicing the area.
The inside of the ionization unit and the area around the DL and heat block
reach high temperatures. Do not access the areas before the temperature
decreases sufficiently. Failure to observe this instruction may result in burn
injury.
Before performing maintenance work, turn the high voltage OFF from the
LabSolutions software.
If you do not turn the high voltage OFF, there will be a danger of electric
shock.
