Replacing the reference probe capillary (NanoLockSpray source) 5-89
4. Locate the PEEK coupler in the union, and carefully slide the
fused-silica capillary into the union until it butts against the pin-plug
capillary locator.
Rationale:
The pin-plug capillary locator correctly locates the capillary
in the union and ensures a minimum dead volume when fitting the
TaperTip.
5. Tighten the PEEK coupler to hold the capillary in place.
6. Unscrew and remove the pin-plug capillary locator.
7. Align the PEEK coupler in the end of the union and slide the TaperTip
into the union until it butts against the fused-silica capillary.
8. Finger-tighten the coupler to hold the TaperTip securely without
crushing.
9. Mount the reference probe on the NanoLockSpray source.
10. Use the combined 2.5-mm Allen wrench and cone extraction tool to fit
and tighten the 3 reference probe retaining screws.
11. Using an F-130 Finger-tight Nut, connect the fused-silica capillary to
the grounded union in the instrument’s IntelliStart Fluidics system.
12. Connect the reference probe’s cable to the instrument’s high voltage
connector.
Warning:
The reference probe tip is an exposed, fused-silica
TaperTip that is sharp and fragile. To avoid puncture wounds,
handle the probe with care.
Caution:
Ensure that you are inserting the square-cut end of the
TaperTip into the union and not the tapered tip.
Caution:
Overtightening the coupler on the TaperTip crushes the
TaperTip and causes blockages.
Caution:
The fragile TaperTip at the end of the reference probe is
easily broken during insertion into the source.
