Running the System Pressure Test

Running the test from the Agilent Lab Advisor
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
Parts required p/n
5043-0277
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
N O T E
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!
1 Select the system pressure test from the test selection menu.
2 Start the test and follow the instructions.
Make sure to release the pressure by opening the purge valve when the test has
N O T E
completed. Otherwise the pump may generate an overpressure error.

Evaluating the Results

The sum of all leaks between the pump and the blank nut will add up to the
total leak rate. Note that small leaks may cause the test to fail, but solvent may
not be seen leaking from a module.
Please notice the difference between an error in the test and a failure of the test! An error
N O T E
is caused by the abnormal termination during the operation of the test whereas a failure of
a test indicates that the test results were not within the specified limits.
