System Pressure Test
The System Pressure Test is performed to evaluate the leak tightness of the system up to the point where the system is capped off. The test is started from the Services & Diagnostics section in the Agilent Lab Advisor Software or in the Local Controller. Modules such as pump, sampler, column compartments as well as accessories like valves or columns can be included into the flow path for this test.
Preparations:
-
Flush the system with HPLC grade water for several minutes from any solvent channel.
-
Start the System Pressure Test and choose the pressure you want to test the system with. Consider pressure limits of modules or accessories included into the flow path.
-
Choose the channel with HPLC grade water and if you want to include or skip an additional purging step.
-
Click OK and follow the instructions: Place a blank nut into the port up to which you want to test the leak tightness of the system.
The test runs automatically without any further user interaction.
Evaluation:
The result as well as the applied limits are displayed after the automatic evaluation. The limits are:
For a pressure setting ≤ 1000 bar, the allowed leak limit is ≤ 5 µL/min
For a pressure setting > 1000 bar, the allowed leak limit is ≤ 15 µL/min
A report can be displayed, saved or printed by opening it with the Print Result button at the lower right of the screen.
If the test does not pass, check the system for leaks or call a local Agilent representative.
