  Several factors can cause reproducibility issues with Waters Laboratory Equipment. These include air in the flow path (perform an initial wash using the 2707 Console or control panel), a leaking syringe (check syringe mounting and gasket; replace if leaking at the bottom), a leaking syringe valve (inspect and replace if needed), a worn rotor seal (replace the seal and inspect the stator), dead volumes in tubing connections (redo connections with new ferrules and nuts), or a broken degasser (repair and confirm operation).
