| PATENT CLAIMS |
Method for performing electrokinetic chromatography - Providing a capillary electrophoresis reagent comprising an aq phase having a partitioning additive & buffer means for receiving said sample & forming a soln of said analyte & (i) Said partitioning additive selected from the group con sisting of cyclodextrins, polymer ions, proteins & surfactant said partitioning additive in an amount to allow partitioning of analyte from soln to the partitioning additive; (ii) Buffering means at concn to maintain pH 2-7 for neutral to acidic aq phases & pH 7-12 for neutral to basic aq phases, said means comprising a polyamine for partitioning additives which are neutral to acidic & polycarboxylate for partitioning additives which are neutral to basic, said aq phase having a conductivity 0.5-2.0 mS/cm - Forming a soln of analyte in aq phase - Injecting aq phase having soln of analyte into a capillary & imposing a voltage across the capillary to effect sepn of the analyte |
