The sensitivity and ruggedness of chiroptical detectors have improved considerably during the past decade. In this article, the authors examine more than 230 chiral compounds using the latest laser-based polarimetry detector for high performance liquid chromatography (HPLC). They also examine the relationship between optical rotation at the detector wavelength of 675 nm and the sodium D line. In addition, the authors consider the sensitivity, linear dynamic range, and effect of solvent composition on rotation and its general use as an HPLC detector for chiral compounds.
