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 like 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 channel.
2 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.
3 Choose the channel with HPLC grade water and if you want to include or
skip an additional purging step.
4 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 ≤5L/min
• For a pressure setting >1000 bar, the allowed leak limit is ≤15 L/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.
Figure 19 on page 140 shows a typical test run.
