SELECTIVITY ENHANCEMENT IN CAPILLARY ELECTROPHORESIS USING NONAQUEOUSMEDIA

Efficiency and selectivity are two important parameters in separation science in order to facilitate resolution of solutes. High efficiencie s are easily obtained using capillary electrophoresis. Selectivity can be improved using different additives like surfactants or cyclodextri ns. Recently, it has been shown that also non-aqueous capillary electr ophoresis provides large improvements in selectivity and without the u se of the above-mentioned additives.
