Isomeric separations were performed using capillary electrophoresis (CE) instrument, in which SDS-L-Lys-Cu+2 micelle complex was used as a pseudostationary phase. The effect of pH, SDS amount, applied electrical field, pressure, organic solvent ratio and ampicillin D,L-ratios were investigated. Fast,inexpensive and sensitive approach for the simultaneous separation of D,L-ampicillin in both aqueous and real antibiotic sample was performed using CE coupled with UV detector. The separation was achieved in a short period of 7 minutes with high-sensitivity andlow-detection limit of 1.25 mu M by the developed SDS-L-Lys-Cu+2 micelle-chiral selector complexes without using any extra process such as imprinting or spacer arms for the immobilization of the ligands.eninfo:eu-repo/semantics/openAccessAmpicillinCapillary ElectrophoresisMicelleArticle10.33263/BRIAC96.52253396452245332-s2.0-85075714682Q3WOS:000503065300011N/A
