Pearl Nebulizer Cleaner

For all quartz and glass concentric nebulizers

With this device a cleaning solution can be pumped
manually in reverse, through both the sample and gas
passages. Favorite cleaning solutions are - Sigma-Aldrich
RBS-25 diluted about 20x, Deconex similarly diluted; - or
- either of these, but with the addition of 10% methanol.
When the wet-cleaning process is finished, rinse with DI
water and flush dry with compressed air or inert gas.

The diagram below shows the 3 main types of blockages
that can occur in pneumatic concentric nebulizers.

#1 - Deposits at this point are typically
composed of salts coming out of solution. Such
deposits can usually be removed by repeated
rinsing of a concentric nebulizer with an
appropriate solvent.

#2 - This sort of obstruction is the worst type,
capable of breaking the tip of a glass capillary.
If the deposit is insoluble, the only sure way to
remove it is with a PEARL cleaner.

#3 - Deposits inside the capillary may go
unnoticed for quite a while, particularly if the
sample is pumped. Paper and textile fibers are
often at fault. Using the PEARL cleaner
