To remove the ion block assembly:
Warning:
To avoid personal contamination with biohazards, toxic materials, and corrosive
materials, wear chemical-resistant gloves when performing this procedure.
1.
Vent and shut down the mass spectrometer (see the mass spectrometer’s online Help for
details).
Warning:
To avoid personal injury, as well as damage to the roughing pump
and mass spectrometer, disconnect the power cords for the mass spectrometer
and roughing pump from the main power source.
2.
Disconnect the power cords for the mass spectrometer and the roughing pump from the
main power source.
Warning:
To avoid burn injuries, exercise care when handling the column or
other components heated to high temperatures. Wait until the hot components
have sufficiently cooled before you handle them.
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).
3.
Remove the source enclosure (see
Removing the source enclosure from the instrument
).
Rationale:
Removing the source enclosure aids access to the ion block assembly.
4.
Close the source isolation valve (see
Closing the source isolation valve
).
5.
Use the combined 2.5-mm Allen wrench and cone extraction tool to unscrew the four,
captive, ion block assembly securing screws.
