occurs during the liquid removal.
5.7 Position of the nebulizer in the spray chamber
Liquid should be delivered to the nebulizer using an identical plastic tubing connector but with
narrow bore tubing (0.50mm inner diameter). Push the white plastic tubing connector with the
attached narrow bore sample tubing into the rear of the nebulizer as far as possible without
exerting undue pressure.
The O-rings in the spray chamber should be inspected and replaced if any wear, or damage, is
visible. Using a twisting motion, insert the nebulizer into the spray chamber so that the nozzle is
level with the arc of the edge of the spray chamber. Small movements in and out are required to
optimize the measurement precision.
Modern designs of nebulizers have a collar to set the depth into the spray chamber. By inserting
the nebulizer into the spray chamber so that the collar is a tight fit the nebulizer will have the
insertion depth optimized and this will aid reproducibility of results.
Attach the quartz glass spray chamber adaptor to the spray chamber with the fitting clamp
provided.
Warning: The adaptor provided with the instrument is specially designed to prevent UV radiation
escaping from the torch box.
