Polarimetry and Optical Rotation of Sucrose and l-menthol
Polarimetry and Measurement of Sucrose and Menthol
Polarimetry is the measurement of the optical rotation of a substance that rotates the plane of polarization of linearly-polarized light as it passes through it. This is more specifically defined as the property of an optically active substance where the refractive indices for left and right circul...
Optical Rotation Measurement for Small Sample Amounts
P-2000 for Optical Rotation Measurement
Optical rotation measurement is a common analytical method used for the evaluation of synthesized compounds and compounds isolated and purified from natural products. In most of cases, the amount of material obtained during synthesis and those obtained from natural product purification is usually very small...
High Accuracy Optical Rotation Measurement of Pirarubicin using Sodium and Halogen Lamps
P-2000 Digital Polarimeter
The phenomena of optical was first identified more than two centuries ago. This measurement was popularized by the use of a convenient low pressure sodium lamp with a strong emission line at 589nm.
In modern polarimeters emission lines of light sources such as a sodium and mercury lamps are often used to measure the high ...
