HyperSep™ Retain™-AX polymeric SPE material is a high purity, highly porous polystyrene DVB (divinyl benzene) material partially functionalised with quaternary amine groups to give balanced retention of acidic and non polar analytes. HyperSep™ Retain™-AX is ideal for the retention of THC and its metabolites.

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

HyperSep™ Retain™-AX 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™-AX. This can lead to fast, reproducible sample preparation and method development.
