Most Frequently Asked Questions

1. What is a semi-automatic polarimeter?

Ans. A semi-automatic polarimeter is a laboratory instrument used to measure the optical rotation of substances. It requires manual sample placement but provides digital reading and analysis.

2. What is the working principle of a semi-automatic polarimeter?

Ans. It works based on the principle of optical rotation, where polarized light passes through an optically active substance, and the angle of rotation is measured.

3. What are the applications of a semi-automatic polarimeter?

Ans. It is commonly used in pharmaceutical, chemical, food, and research industries to measure sugar concentration, purity of compounds, and concentration of optically active substances.

4. Does a semi-automatic polarimeter require calibration?

Ans. Yes, periodic calibration using standard substances is essential to ensure measurement accuracy and reliability.

5. What factors can affect the accuracy of a semi-automatic polarimeter?

Ans. Temperature, sample clarity, and correct calibration are important factors that affect the accuracy of measurement.
