title: Determination of "Brompton's cocktails" by circular dichroism.
abstract: Circular dichroism spectropolarimetry has been applied to the simultaneous determination of chiral compounds in binary mixtures without separation or sample preparation steps. A strategy which uses data measured at equivalent wavelength pairs simplifies the calculations. Correspondence is within +/- 2% of the compositions of prepared standard mixtures.
