To fit the ESI probe tip and gasket:
1. Fit the new metal gasket into the probe tip.
2. Fit the probe tip over the capillary, and screw the tip onto the probe
assembly.
3. Use the 10-mm wrench to tighten the probe tip.
4. Use the nebulizer adjuster knob to adjust the capillary so that it
protrudes by approximately 0.5 mm from the end of the probe.
5. Fit the ESI probe to the source (see page 3-2 ).
Replacing the ESI probe sample capillary
Replace the stainless steel sample capillary in the ESI probe if it becomes
irreversibly blocked or if it becomes contaminated or damaged.
