Polarimetric Estimation of Sugars - SlideShare

↘Reasons to use sucrose solution for calibration of polarimeter : Sucrose is a disaccharide, mixture of both glucose and fructose has a fixed rotation value which can calibrated with 10%, 20% and 30% sugar value, and remains constant for those . concentration for a little time only, upto that we can have a very sharp reading calibration of ...

<781> OPTICAL ROTATION

In making the above exploratory use of the polarimeter, using the sugar solution, you doubtless had to turn the eyepiece clockwise rather than counterclockwise to reach the new extinction point. It is on this basis that sucrose is considered to be dextrorotatory, often shortened to dextrorotary, dextro or d+.

Why sucrose is used in polarimeter calibration? - Answers

Polarimetry basically measures the angle of rotation of polarized transverse waves (e.g:electromagnetic: light) -or polarization- as it passes through an optically active fluid such as sucrose which is a nearly ideal sugar for testing and calibration.
