Characterization of peak purity by fast multiscan circular dichroism detection

A method has been developed to detect inhomogeneity of apparently homogeneous peaks of very similar analytes. The method utilizes the rapid scan feature of state-of-the-art spectrometers/detectors that allow the recording of up to 30 spectra in a single chromatographic peak. Sensitivity and selectivity are enhanced by chiroptical/optical detection. Thus, identification of 'front' and 'rear' components of the peak can be carried out. The method is exemplified by mixtures of codeine, hydrocodone and oxycodone as analytes.
