CAPILLARY ELECTROPHORETIC SEPARATION OF HERBICIDAL ENANTIOMERS APPLYING ERGOT ALKALOIDS

The capillary electrophoretic separation of some herbicidal enantiomer s is shown applying 1-allylterguride as chiral selector. Baseline sepa ration is shown for the enantiomers of fluazifop, halossifop and fenox aprop, whereas the optical isomers of flamprop could be partially reso lved. Separation times are short compared to similar analyses, applyin g HPLC and a terguride chiral stationary phase. The degree of dissocia tion of the acidic analytes, as well as the amount of methanol present in the background electrolyte, are shown to have a major influence on enantioresolution, as expected form earlier studies.
