Polar Enhanced Polymer Stable Across pH Scale
Thermo Scientific HyperSep Retain PEP (Polar Enhanced Polymer) is composed of high-purity, porous polystyrene-divinylbenzene (PS-DVB), modified with hydrophilic functional groups, it gives retention of polar and non-polar analyte types. The material is stable across the entire pH scale for use with any solution. Eliminating the issues associated with the use of silica-beads, such as sorbent material drying, this method of solid phase extraction is suitable for separating drugs, metabolites and peptides in biological fluids, as well as peptides in serum or plasma.
In addition to the PEP, Thermo Scientific HyperSep Retain-CX offers enhanced retention for basic compounds and HyperSep Retain-AX provides enhanced retention for acidic compounds. All chemistries enable fast and easy sample preparation method with high and consistent levels of recovery.
