2. Thread the sleeved fused-silica capillary through the body of the NanoLockSpray reference
probe.
3. Slide a PEEK coupler over the end of the 75-µm fused-silica capillary.
4. Fit the stainless steel wire plug to the inlet end of the sprayer.
5. Locate the fused-silica coupler in the top end of the union and carefully slide the 75-µm
fused-silica capillary into the union until it butts against the stainless steel wire plug.
Rationale:
Doing so ensures a minimum dead volume.
6. Tighten the PEEK coupler to hold the capillary in place.
Warning:
reference-probe tip is an exposed, fused-silica TaperTip emitter that is sharp and
fragile.
7. Remove the stainless steel wire plug.
8. 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 75-µm fused-silica capillary.
Important:
Ensure that you are inserting the square-cut end of the TaperTip emitter in the
union and not the tapered tip.
Notice:
To avoid crushing the coupler on the TaperTip emitter, do not
overtighten it; overtightening can cause blockages.
