Pathfinder® AQ C18 HPLC Columns

The Pathfinder® AQ stationary phase is specially designed to separate highly basic compounds without additives in the mobile phase, a result which has not yet been observed in reversed phase chromatography for silica based stationary phases.  This phase incorporates embedded polar groups into a polymer structure producing a highly base deactivated column having virtually silanol free surface. As a result Pathfinder AQ columns enable the analysis of basic compounds without the use of modifiers in mobile phases. Separations can be optimized by suppressing residual electrostatic interactions between solutes and the stationary phase using only elevated temperatures.
