Hydrosphere c18 is ultra pure silica and unique selectivity leads to a stationary phase that fulfils the relevant requiments of HPLC users.
 Mimal metal content and very low concentrations of residual silanols make this the ideal phase for the analysis of basic pharmaceuticals and chelating compounds even under LC-MS conditions(a seperation in non-phosphate buffered systems).In addition the possiblity to seperate polar compounds under high aqueous mobile phase conditions.
