(6) We describe a fluorescence polarization assay for use in predicting fetal lung maturity, which is suitable for the TDx Analyzer (an automated fluorescence polarimeter). (7) The recent development of laser-based polarimeters with microdegree sensitivity has increased the applicability of optical rotation detection in HPLC. Principle of Polarimeter. Plane-polarized light is generated after natural light passes through the polarizer. If the optically active material is contained in the polarizer, when the polarized light passes through the material solution, the angle of the polarized light will be rotated to the left or right by a certain angle.
Understanding the Basics of a Polarimeter. A polarimeter is a device that detects the rotation of plane-polarized light as it passes through an optically active substance. This substance could be in the form of a liquid, a solid, or a solution. The degree of rotation is proportional to the optically active compound concentration and the length of the sample tube.
Polarimetry is a technique used to measure the rotation of polarized light as it passes through a sample.It is based on the principle that certain substances, such as chiral molecules, rotate the plane of polarization of light. In this article, we will explore the principles of polarimetry, its applications, and the trends shaping the industry.
The polarimeter adopts the principle of photoelectric automatic balance to carry out the optical rotation measurement, and the measurement results are displayed digitally. It not only maintains the advantages of stability and reliability but also makes up for its inconvenient reading. The fluorescence polarimeter used in this research comprised a measurement chamber and a rotating analyzer.
