3-4 Preparing the ESI Source
ESI probe, mounted on the source enclosure
4. Tighten the probe locking ring to secure the probe in place.
5. Connect the ESI probe’s cable to the high voltage connector.
6. Open the access door to the fluidics valve (see the figure on page 1-4 ).
7. Using tubing greater than or equal to 0.004-inch ID, connect port 2 (the
top port) of the diverter valve to the ESI probe.
Recommendation:
To reduce peak broadening, use 0.004-inch ID tubing
for sample flow rates  1.2 mL/min; use 0.005-inch ID tubing for sample
flow rates  1.2 mL/min.
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.
