ABSTRACT:
Circularly polarized monochromatic electromagnetic radiation of a wavelength correlating the maximum absorbance of a sample compound is directed through a flowing solution containing the sample compound, which exhibits circular dichroism activity, and a plurality of other compounds. Measurement of the circular dichroism effect and comparison of an alternating current signal corresponding to the circular dichroism absorption to a direct current component allows for the constant monitoring of the concentration of the sample compound in the flowing solution. The flowing solution may be under high temperature and pressure and may comprise a supercritical fluid.
