Replacing the APCI probe sample capillary 5-79
To install the new capillary:
1. Use the sharp knife or PEEK tubing cutter to cut an approximately
60-cm (24-inches) length of red PEEK tubing.
Requirement:
Cut the tubing perpendicular to its horizontal axis.
2. Insert one end of the red, PEEK tubing in the probe inlet connector, and
screw the connector, finger-tight, into the PEEK union.
Rationale:
Doing so ensures a minimum dead volume when fitting the
capillary.
3. Fit the UNF coupling to the new capillary.
4. Use the needle-nose pliers to slide a new ferrule onto the capillary.
5. Insert the capillary in the PEEK union, and ensure that it is fully
seated.
6. Screw the UNF coupling into the PEEK union, finger-tight only.
7. Gently tug on the capillary, testing to ensure that it stays in place.
Warning:
The probe and source components can be contaminated
with biohazardous and/or toxic materials. Always wear
chemical-resistant, powder-free gloves while performing this
procedure.
