文摘

A microwave-assisted grafting method to attach acrylic acid is described for the first time for chromatographic phases. A high-density, weak cation exchange surface is created on a nylon 6 C-CP fiber support. Vast improvements in dynamic loading capacity and chromatographic performance are realized over native nylon 6 phases. Modification of the fiber surface introduces no deleterious effects on the column kinetic performance.
