Puritas DIOL


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.
