1 500 ml Isopropanol
Preparations • Place two bottles of LC-grade isopropyl alcohol in channels A2 and B2.
• The EMPV is not designed for pressure tightness towards the waste port. Install the manual
purge valve from the accessories kit to pump head A.
• Move the inline filter outlet capillary from the EMPV to to manual purge valve.
NOTE
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 definitely will cause the test to fail!
NOTE
Make sure to release the pressure by slowly opening the purge valve when the test has
finished.
