Perform an Analysis at Ice Water Temperature
- Create a sample file using the analysis conditions and adsorptive properties for water. To replace parameters from the Analysis Conditions parameter file created previously in this document, use the Replace All button on the Sample Description tab.
- Degas the sample to its required conditions.
- Prepare the ice-slush bath and place on the elevator.
- Transfer the sample tube from the degas port to the analysis port.
- Manually evacuate the sample using the instrument schematic.
- Ensure all valves are closed.
- Open valves N2 and PS.
- Open valves 5 and 7. When 760 mmHg is achieved, close valves 5 and N2.
- Open valve PV. Wait approximately 10 seconds, then close valves PV and PS.
- Open valves 9 and 2.
- At 10 mmHg, open valve 1 and close valve 7.
- At 10 mmHg, evacuate for 30 minutes.
- Raise the elevator.
- Start the analysis.
