hypurity cyano columns are based on the unique hypurity silica, designed to be essentially metal free and exceptionally stable at low ph. the hypurity silica manufacturing process ensures reproducibility and quality, and the homogeneous surface leads to uniform bonding coverage and reduced silanol-analyte interactions that result in poor peak shape for bases, acids and chelating compounds. the 190? pore size and excellent mass transfer properties of hypurity packings make them useful for the chromatography of large peptides as well as small molecules, with unbeatable peak shape for all sample types. hypurity columns have proven performance for the separation of peptides and components of tryptic digests. hypurity cyano columns can be used in both reversed phase and normal phase separations. in normal phase, hypurity cyano columns offer alternative se-lectivity to silica phases. in reversed-phase, hypurity cyano columns offer alternative and faster se-lectivty than many alkyl type phases (c18/c8). other column dimensions and hardware designs are available. please contact us for more information if you do not see the exact column that you are interested in. |
