Cleaning the Cyclonic Spray Chamber
If you have been analyzing aqueous solutions, the spray chamber should be cleaned
in an acid bath. An ultrasonic bath may be used. Start with a solution of 5% nitric
acid or aqua regia and, if deposits persist, increase the acid concentration, up to 20%
if necessary. Acid solutions must be used with care. Observe all of the
manufacturer's safety recommendations. These recommendations are normally
provided in a material safety data sheet (MSDS) supplied with the chemical.
If you have been analyzing organic solutions, the spray chamber can be cleaned
using a solvent or diluted soap solution.
O-rings may be cleaned with soap and water. An ultrasonic bath may be used.
Installing the Cyclonic Spray Chamber
See the procedure on Connecting the Cyclonic Spray Chamber on page 138.
Caution
Attention
Do not use solvents that will attack quartz or glass. The cyclonic spray
chamber is not HF resistant.
