3. Fit the UNF coupling to the new capillary.
Requirement:
Use a UNF coupling with no grooves, which is appropriate for the
IonSABRE II probe.

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.
8. Use the 7-mm wrench to tighten the locknut against the PEEK union.
Warning:
goggles when performing the leak test.
9. Perform a leak test by attaching the free end of the PEEK tubing to an LC pump and
pumping 50:50 acetonitrile/water through it at 1 mL/min.
• If leakage occurs, disassemble and remake the connection, and repeat the leak test.
• If the backpressure on the LC pump is high, replace the capillary, and repeat the leak
test.
10. When no leakage occurs and the backpressure on the LC pump is normal, disconnect the
PEEK tubing from the LC pump.
