Retention Loss of Reversed-Phase Columns Using Highly Aqueous Mobile Phases: Fundamentals, Mechanism, and Practical Solutions
We investigate a phenomenon observed by many practitioners of reversed- phase LC: a dramatic loss in retention volume or time after the column flow is stopped and resumed when using highly aqueous mobile phases with certain columns.
