Nebulizer
Installing the nebulizer
1 Insert the nebulizer part way into the spray chamber.
Do not hit the tip of the needle as you insert the nebulizer. The tip of the needle

is easily damaged.
2 Connect the nebulizer sample line to the nebulizer.
3 Turn the nebulizer clockwise and lock it in place.
4 Connect the sample nebulizer gas tubing to the nebulizer.
Do not over-tighten the LC fitting. An over-tightened fitting can crush the

to ensure a stable spray from the CDS to the nebulizer. An unstable spray may
lead to issues with tuning and sample analysis.
