Installing the GemCone Nebulizer on the Cyclonic Spray Chamber
1. Before inserting the GemCone nebulizer into the chamber, connect the argon
gas fitting to the nebulizer threads. First, tighten the gas fitting by hand.
Tighten the fitting another 1/8 of a turn using a 9/16-in. open-end wrench.
Support the nebulizer with a back-up wrench when tightening or loosening
fittings. Do not overtighten the fitting as this may cause leaking and poor ICP
performance.
2. Connect the capillary tubing to the nebulizer. Be sure not to crimp or bend the
tubing as you insert it. Crimps may reduce flow to the tip of the nebulizer or
may cause air to enter the liquid stream during operation.
3. Insert the nebulizer into the cyclonic spray chamber as shown in the next
figure. The spacer that is used on the concentric nebulizer must be used here as
well, so the neb won't be inserted to its fullest extent, it will only go in up to
the spacer.
