Scott Spray Chamber
Check the spray chamber periodically for leaks around the nebulizer end cap and
drain fitting. Examine the end cap O-ring for cracking and wear and replace if
necessary. Deposits and plated out metals can accumulate in the spray chamber,
which can introduce "memory effects." Usually, aspirating a strong acid or solvent
will clean out these deposits. If not, remove the spray chamber and clean it in a 5%
to 20% nitric acid bath
Removing the Scott Spray Chamber
1. Place the sample tubing in deionized water and turn on the pump to flush the
spray chamber. Remove the sample tubing from the deionized water and
continue to run the pump a few minutes until the spray chamber is fully
drained. Then turn off the pump.
2. Disconnect the spray chamber drain tubing from the pump tubing for the drain.
Be careful not to have liquid spill out of the disconnected drain tubing. Spilled
liquid should be cleaned up immediately. Check that the tubing is in good
condition and replace if necessary
