Enantiomeric Separation of Dansyl-Derivatized DL-Amino Acids by β-Cyclodextrin-Modified Micellar Electrokinetic Chromatography Cheng-Fang Tsai, Chin-Fung Li, and Hung-Min Chang* Graduate Institute of Food Science and Technology, National Taiwan University, Taipei 106, Taiwan
β-Cyclodextrin (CD)-modified micellar electrokinetic chromatography (MEKC) was applied to enantiomeric separation of Dns (dansyl-derivatized)-DL-amino acids with sodium dodecyl sulfate (SDS). Increase in the pH value and SDS concentration of the background electrolyte (BGE) buffer solution was found to prolong the migration time and improve the resolution (Rs) of Dns-DL-amino acids. Rs of each DL-amino acid was
