1 Shut off the flow of LC solvent.
2 Shut off the flow of nebulizing gas.
3 Slide back the plastic cover from over the nebulizer.
4 Disconnect the LC tubing and nebulizing gas tubing from the nebulizer.
5 Turn the nebulizer counterclockwise until it disengages from the retaining
screws.
6 Gently lift the nebulizer out of the spray chamber.
Recent residue should be soluble in the mobile phase. If you are not sure what mobile
phase was used recently, a mixture of 50% isopropanol and 50% water works well as
a general cleaning solution.
The tip of the nebulizer may be very hot. Allow it to cool before handling it.
