Warning:
To avoid puncture wounds, take great care working with the source
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:
To avoid recontaminating the components, wear clean, chemical-resistant,
powder-free gloves for the rest of this procedure.
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
Opening the source isolation valve
).
4.
Fit the source enclosure (see
Fitting the source enclosure to the instrument
5.
Close the source enclosure.
6.
Connect the power cords for the mass spectrometer and the roughing pump to the main
power source.
4.15 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.
4.15.1 Handling the StepWave ion guide assembly
Notice:
To avoid damaging the StepWave ion guide assembly, handle it and its
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.
4.15.2 Removing the ion block support from the source assembly
Required materials
• Chemical-resistant, powder-free gloves
• 3-mm hex wrench
• O-ring removal kit
