Equisil APS is an aminopropyl-modified HPLC column based on fully porous, high-purity silica, designed for polar compound separations in HILIC, normal-phase, and weak anion-exchange modes. The aminopropyl functionality provides polar retention and selective interaction with sugars, organic acids, and hydrophilic molecules, making Equisil APS a versatile column for both analytical and routine use.
Equisil APS delivers flexible retention mechanisms for polar analytes – ideal for laboratories requiring HILIC and normal-phase capability in one robust column.
