What is the practical significance of the determination of spin

The spin method can be used for the quantitative determination or purity test of various optically active substances. The sample is prepared into a certain concentration of solution in a specified solvent, and the specific spin is calculated from the measured spin, and compared with a standard, or a standard curve is made with different concentrations of solution to find out the content. On the basis of the spinometer, a sugar meter was also developed, which was specially used to measure the sucrose content. Using white light as the light source, using a quartz wedge to offset the dispersion of sucrose solution to different wavelengths of light, and calibrate the quartz wedge, labeled with the percentage content of sucrose, the concentration can be measured directly, simple and rapid, commonly used in the sugar industry.
