System Pressure Test

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:
1 Flush the system with HPLC grade water for several minutes from any solvent
2 Start the System Pressure Test and choose the pressure you want to test the
3 Choose the channel with HPLC grade water and if you want to include or skip

Evaluation:
The result as well as the applied limits are displayed after the automatic
evaluation. The limits are:

If the test does not pass, check the system for leaks or call a local Agilent
representative.

which you want to test the leak tightness of the system.
The test runs automatically without any further user interaction.
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
