The polarimeter is an instrument for measuring the optical rotation of a substance. Through the measurement of the optical rotation of a sample, the concentration, content and purity of the substance can be analyzed and determined. He Ping and Zhang Jingjing from Yingkou Institute of Technology wrote the article "Application of Polarimeter in Food Analysis", which mainly expounded the application of polarimeter in food analysis, including the determination of sugar content in food and the determination of gluten in food. The method for the content of sodium bicarbonate expands the range of use of conventional experimental instruments.
Finally, it is concluded that polarimeters are widely used in food analysis, and also play an important role in drug analysis and detection of food additives. In addition to measuring the content of optically active substances, polarimeters can also be used for chemical analysis, real-time detection of processes or determination of chiral substances when used in conjunction with other instruments. According to the working principle of the polarimeter, it can also be used to detect the volume concentration of two liquids mixed.
