Quantitative Structure-Retention Relationships of benzoylphenylureas and similar compounds have been studied on a new type of stationary phase (polystyrene-octadecene-encapsulated zirconia) in reversed-phase high performance liquid chromatography. Using stepwise regression analysis, the relationship
## Abstract The low temperature effect has been investigated in reversed phase micro high performance liquid chromatography with various aqueous mobile phase systems by an approach based on enthalpyβentropy compensation. The compensation temperatures, Tc, were determined for these systems, and the
