Polarimeters
GAO’s chemical polarimeters are used to measure the optical rotation of a substance. Optical rotation is the amount by which the plane of polarized light is rotated as it passes through a sample of a chiral substance, such as a molecule that has a non-superimposable mirror image. They work by passing a beam of polarized light through a sample and measuring the angle of rotation of the plane of polarization caused by the sample.
GAO’s chemical polarimeters are composed of a light source polarizer, sample cell, analyzer, detector, display, temperature control device, and power supply.
The other common names of polarimeters are optical rotation meters, polariscopes, polarizing angle detectors, chiral light analyzers, dextro-rotary detectors, levogyre gauges, rotational polarizers, optical activity analyzers, polarizing light instruments, chiroptical sensors, optical isomer analyzers, circular dichroism detectors, polarimetric analyzers, chirality meters, luminar polarimeters, opto-rotational devices, stereochemical analyzers, optical stereochemistry detectors, enantiomeric analyzers, chirality measurement devices, polarized light analyzers, optical active substance identifiers, rotation angle gauges, chiral molecule detectors, dextrorotation analyzers, chirality sensing devices, specific rotation meters, enantiomer identifiers, polarimetric spectrometers, light rotation detectors.

GAO’s chemical polarimeters have the following functions:
- Determination of Optical Activity- GAO’s chemical polarimeters are used to determine the optical activity of a substance, which is a measure of how a chiral molecule interacts with polarized light. The direction and degree of rotation of the polarized light provide information about the sample's optical activity.
- Quantitative Analysis of Concentration-Â GAO chemical polarimeters can be used to determine the concentration of a chiral compound in a sample. By measuring the rotation of polarized light, the concentration of the chiral compound can be quantified.
- Determination of Enantiomeric Purity- Our chemical polarimeters are used to determine the enantiomeric purity of a sample, which is a measure of the ratio of the two enantiomers (mirror-image isomers) present in a chiral compound.
- Study of Reaction Kinetics- GAO’s chemical polarimeters can be used to study reaction kinetics in chiral systems. By measuring changes in the degree of rotation of polarized light over time, information can be obtained about the rate and mechanism of reactions involving chiral molecules.
GAO’s chemical polarimeters are rugged, portable, versatile, and precision measurement instruments. They comply with applicable industry standards such as ASTM E275-02, ASTM E1845-97(2016), ASTM E2255-19, and USP Chapter <781>.
Our chemical polarimeters comply with relevant U.S. government regulations such as:
- Good Laboratory Practices (GLP)
- Current Good Manufacturing Practices (cGMP)
- Title 21 Code of Federal Regulations (CFR)
- Occupational Safety and Health Administration (OSHA)
- Environmental Protection Agency (EPA)
Our chemical polarimeters comply with relevant Canadian government regulations such as:
- Good Manufacturing Practices (GMP) regulations
- Canadian Food and Drug Regulations
- Hazardous Products Act and Workplace Hazardous Materials Information System (WHMIS)
- Canadian Environmental Protection Act
GAO’s chemical polarimeters have the following applications:
- Pharmaceutical Industry- GAO’s chemical polarimeters can be used in the pharmaceutical industry to determine the enantiomeric purity of chiral drug molecules. This is important because many drugs are chiral and only one enantiomer may be effective or safe for use, while the other enantiomer may be inactive or have harmful side effects.
- Food Industry- Our chemical polarimeters are used in the food industry to determine the authenticity and purity of food products such as honey, sugars, and juices. These products can be easily adulterated, and the use of polarimeters can help detect any fraudulent activity.
- Chemistry Research- GAO chemical polarimeters are used in chemical research to study the behavior of chiral molecules in chemical reactions, investigate reaction mechanisms, and develop new synthetic methods for chiral compounds.
- Quality Control-Â Our chemical polarimeters can be used in various industries, including pharmaceuticals, chemicals, and food, as a quality control measure to ensure that products meet the required standards and specifications.
- Environmental Science- GAO’s chemical polarimeters can be used in environmental science to study the behavior of chiral molecules in the environment, investigate the fate and transport of pollutants, and monitor environmental contamination.
Our chemical polarimeters can be shipped overnight within the continental U.S. and Canada, and can be shipped globally.
