Strong retention of hydrophilic compoundsCan be used with 100% water mobile phaseSuperior separation of basic compoundsExcellent reproducibilityUtilizes highly pure silica gel baseTwo types of test reports are included with each columnHydrosphere C18 is designed to maintain adequate hydrophilicity on the packing surface for superior separation of hydrophilic compounds. Hydrophilic compounds are retained with much greater affinity than with conventional ODS columns, permitting the product to be used with 100% water eluent, a problematic eluent for conventional ODS columns. Hydrosphere C18 is useful for separating a wide range of compounds, including nucleic acids and their derivatives, organic acids, saccharides, glycosides and peptides.
