NULL Hamilton PRP-1 (Polymeric Reversed Phase) HPLC columns combine the best characteristics of silica-based and polymeric columns to arrive at a column that is highly inert and long-lasting. Quality assurance as well as research and development laboratories find that PRP-1 columns last significantly longer than silica-based C8 or C18 columns. - Good sample recovery. - Excellent durability (stable to any concentration of water or organic solvent). - Polymeric columns for general separations. - pH stable from 1 to 13: better sample recovery than silica based columns. Fields of application: - Polyacrylic aromatic hydrocarbons (PAH). - Ionised organic compounds. - Steroides. - Peptide fragments. - Pharmaceutical substances. - Nuclein acids. - Vitamins. - Herbicides.
