Abstract:
1. An optical rotating power measurement method for obtaining optical rotating power data of a sample at a predetermined temperature by using an optical rotating power measurement apparatus provided with a sample temperature controller for controlling the temperature of the sample such that the temperature reaches the predetermined temperature, comprising: an optical rotating power data acquisition step of obtaining two or more temperature data and optical rotating power data of the sample at each of the temperature data during a temperature changing process where the sample temperature controller controls the temperature of the sample such that the temperature reaches the predetermined temperature; and a data processing step of setting a temperature range of the optical rotating power data used to obtain a regression straight line data based on temperature dependence data of the sample, and obtaining the regression straight line from the temperature data and the corresponding optical rotating power data within the temperature range; wherein the optical rotating power data of the sample at the predetermined temperature is determined based on the regression straight line.
