to the end of the nebulizer.

d Connect the sample transfer line.
Attach the transfer tube from the end of the torch to the spray chamber

Testing the Nebulizer and Spray Chamber
Perform the basic maintenance test explained in 'Testing after Maintenance'
later in this chapter. Check the gas pressures and flow rates in the Instrument
Control window to determine if the gas hoses are connected tightly. See
Chapter 3, “Startup, Shutdown and Status” in this manual for more
information. Also check for leaks in the sample uptake connections. Liquid
leaks are collected in the tray under the spray chamber and expelled out of the
drain hole on the left side of the tray.
CAUTION
Do not over-tighten the nuts or the quick-connect clamps. The glass will break if too
much pressure is applied.
