catch any particles before they get into the nebulizer. It is much safer & easier to
replace the capillary tubing than to clean the nebulizer.
The Mira Mist Nebulizer body is PEEK, and the inner capillaries are Teflon.
Generally it will not break. If it is dropped such that the tip is deformed, then it will
be irreparably damaged. If it continues to operate after being dropped, then it has not
been affected, and its use can be safely continued.
Gas Line
The gas line is attached with UpChurch® 10/32 chromatographic fittings (Part No.
N0777113). We supply 2 mm OD X 0.039 ID Teflon tubing. A gas line filter is
NOT
included in the nebulizer. Any particles from the gas line will destroy the 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 200 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.
