• 6-mm (¼-inch) wrench
To replace the ESI probe tip

2. Use the 6-mm (¼-inch) wrench to unscrew and remove the probe tip.
3. Dispose of the probe tip in accordance with local environmental
regulations.
4. Use the 6-mm (¼-inch) wrench to fit and tighten the new probe tip to the
probe.
5. Adjust the probe tip so that the fully extended capillary (when the probe
nebulizer adjuster knob is fully screwed down) protrudes by
approximately 1 to 1.5 mm.
6. Fit the probe to the source (see also page 48 ).
