Journal of chromatography. B, Analytical technologies in the biomedical and life sciences, 772(2), 307-315 (2002-05-15)
A modified specific, sensitive and reproducible chiral gas chromatographic (GC) method for the resolution and quantification of ethosuximide enantiomers in urine and plasma was developed. The samples were extracted by liquid-liquid extraction, using diethylether and the enantiomers were separated and
