Puritas DIOL

 

Overview

PURITASTM Diol phase is a very versatile phase as it can be used both under 'Normal Phase' and 'Reverse Phase' conditions depending on the mobile phase selection. In the normal Phase mode the retention times are lesser than that of bare silica with good resolution and reproducibility. In the reverse phase mode it offers a unique selectivity for a wide range of compounds. Overall it is a very good phase for the separation of both Non-polar and highly polar compounds.

Key Features

  • Suitable for hydrophilic compounds separation
  • Strong retention in aqueous condition
  • Longer lifetime in aqueous eluents
  • Different selectivity from ODS-RPS
  • Enhanced mechanical stability
  • Suitable for easy scale up and preparative analysis
