Procedures for Sample Clean-up and Concentration in Capillary Zone Electrophoresis for Determination of Drugs in Biosamples
Procedures for sample clean-up and concentration in Capillary Zone Electrophoresis (CZE) have been developed for determination of drugs in biosample s. An on-capillary concentration technique based on enhanced field strengths, the double stacking procedure is introduced. This procedure allows for concentrationg all cations in the sample several hundred times essentially without loss of separation
