Preparations • Place a bottle of LC-grade isopropyl alcohol in the solvent cabinet and connect its solvent tube
to the active inlet valve of the pump.
Make absolutely sure that all parts of the flow path that are part of the test are very
thoroughly flushed with IPA before starting to pressurize the system. Any trace of other
solvents, or the smallest air bubble inside the flow path, will definitely cause the test to
fail.
