Abstract
An improved biocompatible filter for use in liquid chromatography systems such as HPLC or UHPLC The present disclosure addresses the problem of particles bypassing a filter in a liquid chromatography application by design features in the interface between the frit filter and ring that form an improved seal between the ring and frit and prevent leakage around the filter in high measure chromatography. Design features also include frit filters with an internal particle size gradient for pre-column separation activity during filtration.
