HyperSep™ Retain™-CX polymeric SPE material is a high purity, highly porous, polystyrene DVB material partially functionalised with sulphonic acid groups to give balanced retention of basic and non polar analytes. HyperSep™ Retain™-CX is ideal for the retention of a wide range of drugs of abuse, including basic and neutral drugs.

• High and consistent recoveries
• Fast and easy sample preparation and method development
• pH stable zero to 14

HyperSep™ Retain™-CX offers reproducible and reliable sample preparation through excellent  batch-to-batch reproducibility. Many of the problems associated with traditional silica-based materials, such as inconsistent recoveries due to sorbent drying, are eliminated when using HyperSep™ Retain™-CX. This can lead to fast sample preparation and method development.
