polarimeter and refractometer|how to calculate polarimeter : companies Because many optically active chemicals such as tartaric acid, are stereoisomers, a polarimeter can be used to identify which isomer is present in a sample – if it rotates polarized light to the left, it is a levo-isomer, and to the right, a dextro-isomer. It can also be used to measure the ratio of enantiomers in solutions. The optical rotation is proportional to the concentration of the optically active substances in solu.

What affects the polarimeter measurement? The optical activity – and thus the measured value – is also influenced by the temperature, the wavelength of the light and the length of the optical path. The length of the optical path is specified by the length of the used polarimeter tube. A longer optical path results in a higher angle of rotation.
Should you use a saccharimeter or a polarimeter?

To select the right refractometer, it is helpful to define the required measurement range. There is real potential for savings when purchasing a new refractometer, as refractometers with a small measurement range are usually more cost-effective compared to measuring devices that cover the entire measurement range.
