6 Maintenance Procedures
4. Locate the PEEK coupler in the top end of the union, and carefully slide
the 75-µm PEEK capillary into the union until it butts against the
internal surface of the union.
Rationale:
5. Tighten the PEEK coupler to hold the capillary in place.
Warning:
The ionKey reference-probe tip is an exposed, fused-silica
TaperTip emitter which is sharp and fragile.
6. Locate a second PEEK coupler in the bottom end of the union and slide
the TaperTip emitter into the union until it butts against the internal
surface of the union.
Important:
TaperTip emitter into the union and not the tapered tip.
Notice:
not overtighten it; overtightening can cause blockages.
7. Finger-tighten the coupler to hold the TaperTip emitter securely,
without crushing.
Notice:
when inserting the ionKey reference probe into the ionKey source
enclosure.
8. Mount the ionKey reference probe on the ionKey source enclosure.
9. Using the combined, 2.5-mm Allen wrench and cone extraction tool,
tighten the three screws that secure the ionKey reference probe.
10. Replace the combined, 2.5-mm Allen wrench and cone extraction tool in
its storage location on the source adaptor housing.
11. Fit the ionKey source enclosure to the instrument (see
12. Using an F-130 "finger tight" nut, connect 75-µm PEEK capillary to the
grounded union in the instrument's IntelliStart Fluidics system.
13. Connect the reference probe's cable to the instrument's high voltage
connector.

Doing so ensures a minimum dead volume.
To avoid puncture wounds, handle the probe with care.
