3-4 Configuring the LockSpray Source
ESI probe, mounted on the LockSpray source enclosure:
4. Tighten the probe locking ring to secure the probe in place.
Tip:
An automatic pressure test is performed when the probe is correctly
seated in position.
5. Connect the ESI probe’s cable to the high voltage connector.
6. Open the access door to the IntelliStart Fluidics system (see the figure
on page 1-12 ).
7. Using a long “finger-tight” fitting, connect 0.004-inch ID (or greater)
tubing, from port 2 (the top port) of the diverter valve to the ESI probe,
where you use a PEEK, “finger-tight” nut and ferrule to connect to the
union.
Caution:
To avoid nitrogen leakage, fully tighten the probe locking
ring.
Warning:
To avoid electric shock, do not use stainless steel tubing
to connect the diverter valve to the ESI probe; use the PEEK
tubing supplied with the instrument.
