5.5 Cleaning the condenser lens
The condenser lens gradually becomes contaminated due to ultraviolet light. Clean
the condenser lens following the procedure below. If you do not provide cleaning at a
proper interval, contaminant deposited inside will cause errors in analysis results.
1 Disconnect the vinyl hose for exhausting argon gas from the spark stand
following step 3 described in "5.3 Maintaining the spark stand".
Be sure to disconnect the vinyl hose prior to cleaning the condenser
lens, or evaporant in the piping or water in the bubbler may flow back
and enter the stand, damaging the instrument.
2 Pull the handle to pull up the condenser lens unit.
3 Remove the lens mounting frame by rotating it with a lens rotating tool.
