Polarimeters
Did You Know?
Did you know that polarimeters have been used for over two centuries to study the properties of light and matter? The first polarimeter was invented by French physicist Etienne-Louis Malus in 1808, and since then, polarimeters have played an important role in scientific research and industry.
Polarimeters are used to measure the rotation of polarized light as it passes through a sample, and this can provide valuable information about the sample's molecular structure, concentration, and purity. In the pharmaceutical industry, for example, polarimeters are used to ensure that the correct optical isomer of a drug is being produced, as this can have a significant impact on the drug's efficacy and safety.
Today, polarimeters come in a range of sizes and levels of automation, from small handheld devices to sophisticated laboratory instruments. They continue to be an important tool for researchers and industry professionals alike, and their applications in fields like chemistry, materials science, and biochemistry are only continuing to expand.

Frequently Asked Questions
A polarimeter is a scientific instrument used to measure the rotation of polarized light as it passes through a sample.
There are two main types of polarimeters: manual polarimeters, which require the user to manually adjust the instrument's components to measure rotation, and automatic polarimeters, which use an automated system to measure rotation.
A polarimeter measures the rotation of polarized light, while a refractometer measures the bending of light as it passes through a sample.
Polarimeters are commonly used in pharmaceutical, chemical, and food industries to determine the concentration, purity, and identity of substances. They are also used in research laboratories to study the properties of materials.
Using a polarimeter allows for precise measurement of a sample's optical activity and can provide information on the sample's molecular structure, concentration, and purity.
Some factors to consider when choosing a polarimeter include the accuracy and sensitivity of the instrument, the type of sample being measured, the level of automation required, and the availability of software for data analysis.
