Frequently Asked Questions
1. What is the difference between a manual and automatic polarimeter?
Manual polarimeters, like the Exacta PL1, require the operator to visually match the brightness of the split field, while automatic (digital) polarimeters use electronic sensors to instantly detect the angle of rotation and provide a digital readout.
2. What are 2-in-1 polarimeters used for?
2-in-1 instruments, such as the ATAGO RePo series, measure both the refractive index and optical rotation simultaneously, making them ideal for determining the concentration and purity of sugar or fragrance samples in one step.
3. What is the standard wavelength for these measurements?
The standard wavelength for most laboratory polarimetry is 589.3 nm (the sodium D line), which is the reference used by models like the Exacta PL1 for consistent international reporting.
4. Can a polarimeter determine the concentration of a sample?
Yes, because optical rotation is proportional to concentration, a polarimeter can be used to measure the concentration of enantiomer-pure samples, such as sugar in a solution.
