Replacing the NanoLockSpray reference-probe TaperTip emitter or capillary
5. Tighten the PEEK coupler to hold the capillary in place.
Warning:
The NanoLockSpray 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.
Ensure that you are inserting the square-cut end of the
Important:
TaperTip emitter into the union and not the tapered tip.
To avoid crushing the coupler on the TaperTip emitter, do
Notice:
not overtighten it; overtightening can cause blockages.
7. Finger-tighten the coupler to hold the TaperTip emitter securely,
without crushing.
To avoid breaking the fragile TaperTip emitter, take care
Notice:
when inserting the NanoLockSpray reference probe into the
NanoLockSpray source enclosure.
8. Mount the NanoLockSpray reference probe on the NanoLockSpray
source enclosure.
9. Using the combined, 2.5-mm Allen wrench and cone extraction tool,
tighten the three screws that secure the NanoLockSpray 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 NanoLockSpray source enclosure to the instrument (see
page 102).
12. Using an F-130 "finger tight" nut, connect the 75-µm sleeved PEEK
capillary to the grounded union in the instrument's IntelliStart Fluidics
system.
13. Connect the NanoLockSpray reference probe's cable to the instrument's
high voltage connector.
To avoid puncture wounds, handle the probe with care.
