title: [Characterization of napropamide enantiomers by CD and determination of the enantiomeric ratios in water].
abstract: The enantiomers of napropamide were separated by normal phase HPLC (HPLC: high performance liquid Chromatography) with Chiralpak OJ-H column and charactered by circular dichroism. On this basis, a method for the chiral separation and micro-determination of napropamide in water was established. The linearity of calibration curve for racemic mixture was 10-100 ng x mL(-1) and the correlation coefficient was 0. 99. When 10 microL was injected, the detection limit of racemic mixture was 8 ng mL(-1), and the detection limits of both enantiomers were 4 ng x mL(-1).
