Abstract
(-)-(18-Crown-6)-2,3,11,12-tetracarboxylic acid-bonded silica was used as the chiral stationary phase in capillary electrochromatography (CEC) for enantioseparation of soiree alpha-amino acids Separation data in CEC were measured in mobile phases of varying pH, and composition of methanol and buffer, anti compared with those in capillary liquid chromatography (CLC) In CEC better enantioseparation was generally obtained in the eluent of lower pH, higher buffer concentration and inter mediate MeOH content. usually at the expense of analysis time CEC showed generally better enantioselectivity and resolutions than CLC for the amino acids investigated.
