HyperGEL OP Columns for Organic Size Exclusion Chromatography HyperGEL? OP columns are designed for SEC using organic solvents. High quality polystyrene/ divinylbenzene provides mechanical stability up to 2,200 psi and temperature stability up to 150 °C. HyperGEL OP columns are available in 7 pore sizes and 2 particle sizes. The 5 ìm columns provide a minimum efficiency of 50,000 N/m and are ideal for high resolution separations whereas the 10 ?m columns are designed for higher molecular weight samples, or demanding solvent or temperature conditions.
HyperGEL AP Columns for Aqueous Size Exclusion Chromatography HyperGEL AP columns are designed for size exclusion chromatography of water soluble polymers, although they are not recommended for proteins (please refer to BioBasic SEC columns on page 62 for size exclusion chromatography of proteins). The columns are packed with macroporous hydrophilic polymer materials providing minimal surface interactions, as well as excellent mechanical and chemical stability.
