TEHRAN (ANA)- Iranian scientists at a knowledge-based company managed to make a refractometer device which can determine the purity level of oil and alcohol, and sugar concentration.
“Refractometer is a device for measuring the refractive index and birefringence of both solid and liquid materials,” said Sajjad Aqajari, a student of Shahid Beheshti University’s Faculty of Physics.
“In this device, the mechanism of light deviation at the desired wavelength is used. It can also be applied for the measurement of reflection at different angles and for the appropriate polarization. Also, the device is used for determining the appropriate physical model of the refractive index and birefringence of the material. This device is also capable of measuring the normal and non-normal refractive index of anisotropic materials,” he added.
“Determining oil purity, sugar concentration, alcohol in food industries, characterizing polymers, liquid crystals in chemical industries, determining gem quality in gemology, characterizing materials in research laboratories are among applications of this product,” Aqajari said.
A refractometer is a simple instrument used for measuring concentrations of aqueous solutions like gases, liquids, and translucent solids. Different types of refractometers are available depending on the application.
Refractometers are used in the laboratory and in many industries including agricultural, food, chemical, and manufacturing industries.
In the lab, refractometers measure the composition of samples from many industries. Some refractometers are designed for challenging samples and provide highly precise measurements.
In the food industry, refractometers have many uses including measuring sugar and salt. Sugar can be measured in a jelly and jam, milk, fruit juice, and other types of beverages. Salt content can be measured in cheese or even in bakery items.
