AquaSep

AquaSep is the clear choice for the discriminating HPLC chromatographer faced with a difficult separation challenge such as polar compounds, compounds requiring a highly aqueous mobile phase or difficult to retain compounds. The AquaSep phase has been specially developed using patented technology for use with highly aqueous mobile phases, including 100% aqueous. Our unique patented approach provides a complete solution to ensure that AquaSep is totally resistant to “phase collapse” under all mobile phase conditions.
