nebulizer. We have found this is one of the main causes of blockage of the
nebulizers, so please ensure that the gas line to the nebulizer is clean of any
particles.
The gas line terminates in the Avio 500 quick disconnect. It is a direct replacement
for typical concentric nebulizers.

Sample Introduction / Maximizing Stability

The Mira Mist does not have any suction, so it requires a pump to supply the
sample solution. The pump speed and the quality of the pump tubing have a large
effect on the performance of the nebulizer. Try to select a pump tubing size that
allows running the pump at a higher speed (If you use the standard black-black
tubing, you may need to use a higher pump rate: for example 1.5 mL/min). So for
low sample flow, use orange green or orange blue pump tubing. Generally the
pump tubing should be changed every day for maximum stability and lowest
%RSD.

Cleaning the Nebulizer

The gas orifice is at the very tip of the nebulizer. It is made of Teflon which

is VERY SOFT. This tip is very easily damaged and should NEVER be
touched with fingers, tissues, or anything else. If the tip is accidentally
touched and the nebulizer continues to operate, then it is still functional,
and its use can be safely continued.

doux. Cette astuce est très facilement endommagé et ne doit JAMAIS être
touché avec les doigts, les tissus, ou toute autre chose. Si la pointe est
accidentellement touché et le nébuliseur continue à fonctionner, alors il est
encore fonctionnel, et son utilisation peut se poursuivre en toute sécurité.
For the longest life and best performance, wash your nebulizer by simply running
water as a sample for 10 minutes at the end of the day before shutting down the
plasma. Any other form of washing is usually unnecessary. DO NOT wash your
nebulizer in acid or solvents to "prevent salt build up". DO NOT use surfactants as
they will destroy the surface tension at the tip and performance.
