6 Troubleshooting and Diagnostics
Pump Self Test
Preparations:
1 Flush the system with HPLC grade water for several minutes from any solvent
channel.
2 Start the Pump Self Test and choose the test you want to test the system with.
The pressure will automatically adjust to best fit your system.
3 Choose if you want to use a blank nut or the sampler (only certain modules) to
block the pump.
4 Choose the channel with HPLC grade water and if you want to include or skip
an additional purging step.
5 Click OK and follow the instructions.
Evaluation:
The result as well as the applied limits are displayed after the automatic
evaluation. The limits are:
• The allowed leak limit for the secondary piston and for any other leakage is
≤3µL/min.
• The allowed leak limit for the primary piston is ≤30 µL/min
• If the restriction for any of the filters is unreasonably high, consider
exchanging the filter frits.
A report can be displayed, saved or printed by opening it with the Print Result.
If the test does not pass, check the system for leaks or call a local Agilent
representative. Figure 18 on page 118 shows a typical test run.
