Reassembling the ESI Probe
To reassemble the ESI probe (that is, to reinstall the ESI sample tube, nozzle,
needle, and needle seal), proceed as follows (see Figure 4-5):
1. Inspect the Teflon needle seal (P/N 00950-00952). If the needle seal is
deformed, replace it.
2. Inspect the 26-gauge spray needle (P/N 00950-00990). If the spray
needle is damaged, replace it.
3. Ensure that the 0.676-in. ID O-ring (P/N 00107-05710) for the sheath gas
on the ESI nozzle is in good condition. In addition, ensure that the O-ring
is placed into the pre-cut groove on the ESI nozzle. See
Figure 4-6.
4. Reinstall the ESI nozzle, needle, and needle seal as follows:
a.
Insert the entrance end of the ESI needle into the needle seal.
b. Seat the ESI needle and needle seal in the ESI manifold.
c.
Install the spiral wave spring into the ESI manifold.
d. Thread the ESI nozzle over the needle and into the ESI manifold.
Slightly wet the nozzle threads with HPLC-grade methanol for
lubrication.
e.
With a 5/16-in. wrench, gently tighten the ESI nozzle until it is a little
more than finger-tight. Do not overtighten.
CAUTION. AVOID ELECTRICAL SHOCK. When you are operation
your instrument in the ESI mode, you could receive an electrical shock
unless you install the safety kit discussed below. You could receive an
electrical shock if the fused-silica capillary tube breaks during ESI
operation. Therefore, for your safety and in compliance with international
safety standards, you must cover the fused-silica capillary tube with the
PEEK safety sleeve (P/N 00301-22806) and associated PEEK ferrules
(P/N 00101-18119) provided in the Safety Sleeve Kit (P/N 70005-62015)
before you operate the instrument. Installation instructions
(P/N 70005-97009) are included in the kit. Operation of the instrument
without the safety sleeve impairs the safety protection provided by the
instrument and, thus, could lead to serious injury.
