Testing For Leaks; Testing Individual Valves; Analysis Valves - Micromeritics ASAP 2020 Confirm Operator's Manual

Appendix D
This appendix contains general instructions for testing the ASAP 2020 and the SmartVac
degasser (if installed) for leaks. If the analyzer successfully performs a blank tube analysis
using nitrogen, you do not need to test for leaks.
These procedures may be performed individually or sequentially. Record pressure readings on
the Valve Test Data Sheet included at the end of this appendix. After you finish testing for
leaks, replace any leaking valves.
You will need the following items to perform tests:
• Stopwatch
• Valve Test Data Sheet (included in this appendix)
An automated method of performing a leak test can be found in .

Testing Individual Valves

Analysis Valves

This procedure removes differential pressure from all valves in the analysis system and estab-
lishes that there are no leaks in the analysis system. It should be performed before testing for
individual valves.
1. Ensure that the analyzer is idle.
2. Close the regulator outlet valve for each gas supply line to the analyzer.
3. Attach the Po tube to the Po port.
4. Insert a plug (or attach a clean, empty sample tube) into the analysis port.
5. Insert a plug into the vapor inlet (if the vapor option is not installed).
