Degas a sample
In some situations, samples may develop air bubbles. To degas a
sample before analysis, refer to steps 1-5.
Note: Some fluids contain volatile constituents that boil off under vacuum
conditions. If a sample boils, stop the degassing operation.
1. Put a sample in the sample chamber
2. Set the pressure/vacuum switch to the vacuum mode.
