Warning:
enclosure open if one or both of these conditions apply:
• An ESI probe is fitted (the probe's tip is sharp).
• A corona pin is fitted (the pin's tip is sharp).
Notice:
powder-free gloves.
1. Fit the ion block assembly to the PEEK ion block support.
2. Use the combined 2.5-mm hex wrench and cone extraction tool to fit, and then slowly
tighten, the four ion block assembly securing screws sequentially and in small increments.
3. Open the source isolation valve (see
4. Fit the source enclosure (see
5. Close the source enclosure.
6. Connect the power cords for the mass spectrometer and the roughing pump to the main
power source.

7.16 Cleaning the StepWave ion guide assembly

Clean the StepWave ion guide assembly if cleaning the ion block and isolation valve fails to
increase signal sensitivity.

7.16.1 Handling the StepWave ion guide assembly

Notice:
components carefully throughout the cleaning procedure.
In particular, to avoid damaging the wiring on assemblies fitted with an externally wired
printed circuit board (PCB), do not touch the wiring.
Notice:
externally wired, do not touch the PCB.
