Leak Check Reaction Vessel
The Reaction Vessel Leak Check should be performed any time the reaction vessel has been
disconnected from the system. In particular, a leak check should be performed when switching
between the 125 mL, 35 mL, and 10 mL vessels, or after any test that requires disconnecting the
spray head line.
To perform a Reaction Vessel Leak Check:
Select the Leak Check Reaction Vessel category, and then click Test.1.
A warning will pop up to conrm that the reaction vessel is connected and secure. 2.
Verify the reaction vessel is properly connected, then click OK.
The Liberty will pressurize the reaction vessel.3.
The pressure will be monitored for a set amount of time, during which the current 4.
drop in pressure at the manifold being tested will be displayed in the status box.
If the pressure drops more than 0.4 psi, the reaction vessel will fail the Leak 5.
Check. (For help with troubleshooting a leaking reaction vessel, see p. 115 or
contact CEM Service.)
Flow Performance
The Flow Performance test is intended to verify there are no restrictions in the lines of the Liberty
by testing the rates of nitrogen ow through all lines and manifolds. Typically, this test is only
performed on the advice of CEM Service to aid in diagnosing a problem. To perform a Flow
Performance test:
Select the Flow Performance Test category, and then click Test.1.
