Application Notes:
Application Columns:
- Primesep® B2 is a mixed-mode HPLC column with general hydrophobic and ion-exchange properties. The Primesep B2 stationary phase combines a hydrophobic chain and a basic functional group as an anion exchanger. Acids, bases, zwitterions and neutrals can be retained and separated by Primesep B2 columns. Primesep B2 also separates bases by an ion-exclusion mechanism. Primesep B2 demonstrates significant improvement in retention and selectivity for the separation of weak acid analytes by a combination of reversed phase and anion exchange. In this case the basic functional group acts as an embedded ion-pairing reagent. Primesep B2 column is one of the best separation media for natural product extracts. Methods can be developed on Primesep columns that are fully compatible with detectors such as UV, RI, conductivity, fluorescence, evaporative light scattering (ELSD) as well as mass spectrometers (LC/MS) and preparative chromatography (prep HPLC) systems.
