Warning:
goggles when performing the leak test.
16. Perform a leak test on the PEEK union and slide port assembly by attaching the free end
of the red PEEK tubing to an LC pump and pumping 50:50 acetonitrile/water through it, at
1 mL/min, ensuring that fluid can be seen leaving the free capillary end.
Important:
Ensure that no fluid is leaking from the joints on the PEEK union. If leakage
occurs, repeat this assembly procedure, and then repeat the leak test.
17. Disconnect the probe inlet connector and red PEEK tubing from the PEEK union.
Notice:
To avoid bending or damaging the protruding end of the capillary after
you thread it through the ESI probe, take care when handling the probe
assembly during the remainder of the procedure.
18. Carefully thread the capillary through the probe assembly until the slide port and PEEK
union assembly reach the top of the probe assembly.
