Running the (System) Pressure Test
Running the test from the Agilent Lab Advisor
1 Select the (system) pressure test from the test selection menu.
2 Start the test and follow the instructions.
When The test should be used when problems with small leaks are suspected, or after maintenance of
flow path components (e.g., pump seals, injection seal) to prove pressure tightness up to 600 bar
Tools required p/n Description
8710-0510 Wrench, 1/4 - 5/16 inch, open
Blank nut 1/16 inch
Preparations Place two bottles of HPLC-grade water in channels A and B (A1 and B1 if the pump is equipped with
a solvent selection valve)
Make absolutely sure that all parts of the flow path that are part of the test are very
thoroughly flushed with water before starting to pressurize the system! Any trace of other
solvents or the smallest air bubble inside the flow path definitely will cause the test to fail!
Make sure to release the pressure by opening the purge valve when the test has
completed. Otherwise the pump may generate an overpressure error.
