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.
