Versatile polymeric material for retention of polar and non-polar analytes.

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

HyperSep™ Retain™ PEP 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™ PEP. This can lead to fast sample preparation and method development.
