Dr. Maisch HPLC Column Hamilton PRP-1, 80Å, 5.0 μm, 4 x 75 mm

Unlike silica-based C8 or C18 columns, PRP-1 has no stationary phase coating. The integral reversed-phase characteristics of the PRP-1 column eliminate the need for special coating techniques. Since there is no stationary phase to hydrolyze, the column maintains its performance characteristics longer than many C8 or C18 columns.
