To adjust the multimode nebulizer
15 Adjust the electrospray needle position before reinstalling the nebulizer in 
the spray chamber.
Take care when inserting the needle. The tapered end of the needle must pass through 
the restrictions in the nebulizer shaft. The tip of the needle can be damaged if 
excessive force is applied. 
Record this procedure in the Maintenance Logbook.
