3-10 Configuring the LockSpray Source
12. Test for leaks by attaching the free end of the PEEK tubing to an LC
pump and pumping mobile phase through it, at 200 µL/min.
•
If leakage occurs, disassemble and remake the connection, and then
repeat the leak test.
• If the back pressure on the LC pump is unacceptably high, replace
the capillary, and repeat the leak test.
13. When no leakage occurs and the LC pump back pressure is normal,
disconnect the PEEK tubing from the LC pump.
14. Remove the PEEK, “finger-tight” nut and ferrule and red PEEK tubing
from the PEEK union.
15. Carefully thread the capillary through the probe assembly.
16. Carefully push the PEEK union/UNF coupling assembly and capillary
into the probe assembly so that the locating pin on the UNF coupling
engages in the locating slot at the head of the probe assembly.
17. Fit the nebulizer adjuster knob to the PEEK union/UNF coupling
assembly.
18. Finger tighten the nebulizer adjuster knob onto the probe assembly.
Warning:
To avoid eye injury from high-pressure liquid jet spray,
wear safety goggles when performing the leak test.
