Installing the GemCone Nebulizer on the Scott-Type Spray Chamber
To install the GemCone nebulizer on the Scott-type spray chamber, the end cap
assembly (Part No. N0680504) and the tubing assembly (Part No. N0770336) must
be used.
1. Remove the existing nebulizer/end cap assembly (if the wrong one is installed)
by loosening the knurled nuts on the end cap. Use a gentle twisting action to
remove the assembly from the spray chamber.
2. Assemble the correct end cap (Part No. N0680504) to the spray chamber with a
twisting action.Alternately hand-tighten the knurled screws until the end cap
ring is pulled snugly against the end cap.
3. Before inserting the GemCone nebulizer into the cap, connect the argon gas
fitting to the threads on the nebulizer where shown in the next figure. 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.
4. 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.
5. Insert the nebulizer as far as it will go through the opening in the end cap.
6. Tighten the nut on the end cap so that it is finger-tight.
