A refractometer is a simple instrument used for measuring concentrations of aqueous solutions such as gases, liquids, and translucent solids. Different types of refractometers are available depending on the application. Refractometers can be handheld, compact, benchtop, Abbe, and Brix as well as different .
In 1857 Jamin (1857 b) made his original application of the methods of interferometry to the measurement of the refractive index of a gas. The increased accuracy obtainable by the use of the principle of the Jamin refractometer enabled Ketteler (1865) to determine the refractive indices of air for the red, yellow and green lines in the visible .interferometer,7-8 Jamin or Rayleigh refractometers.9 More complex configurations are reported, e.g. combining two Michelson interferometers,10 or inserting a very stable stepped cell in an arm of the interferometer,11 or using grating interferometers.12-13 .A Jamin refractometer is a device for measuring or for comparing the indexes of refraction of gases. A beam of monochromatic light is split into two parts, each of which is directed along the axis of a separate cylindrical tube before being recombined into a single beam that is viewed through a telescope.This refractometer system operates on a resonant-sensing principle in which variations in the refractive index of a test analyte could be detected by measuring the transmission spectrum shift of the sensor system. The resolution of the all-fiber refractometer was found to be on the order of 10 −5 to 10 −4 RIU (refractive index unit). We .

A novel two-beam interferometers for the measurement of a refractive index or its induced changes is described, which uses a polarized version of the folded Jamin interferometer to allow for convenient phase adjustment. A novel two-beam interferometer for the measurement of a refractive index or its induced changes is described. This interferometer consists of only .
Refractometers are widely used to measure the amount of dissolved substances in solutions containing mainly sucrose. The relationship between refractive index and the amount of dry substance content is well known for sucrose and is the basis of the BRIX scale, which is the measure of the number of grams of sucrose present per 100 grams of aqueous sugar solution.This site uses cookies.

Close this notificationThe Jamin interferometer is a type of interferometer, related to the Mach-Zehnder interferometer. It was developed in 1856 by the French physicist Jules Célestin Jamin. The interferometer is made up of two mirrors, made of the thickest glass possible. The Fresnel reflection from the first surface of the mirror acts as a beam splitter.
In the course of an investigation of the refractivity of gaseous bromine conducted with a Jamin refractometer it was observed that, as the temperature changed, very slight variations of the density of the vapour could be quickly and accurately recorded. This fact suggested that an optical method would be useful for measuring vapour pressures or .Refractometry is the analytical method of measuring substances' refractive index (one of their fundamental physical properties) in order to, for instance, assess their composition or purity.A refractometer is the instrument used to measure refractive index ("RI"). Although refractometers are best known for measuring liquids, they are also used to measure gases and solids, such .

Refraktometer menjadi alat yang tak tergantikan di berbagai industri kimia karena mampu mengukur konsentrasi suatu substansi dengan cepat dan akurat. Answer of - A Jamin refractometer is a device for measuring or comparing the indexes of refraction of fluids. A beam of monochroma | SolutionInn
A modification of the Jamin refractometer is described in which each of the thick glass plates is replaced by two thin plates, separated by steel balls. It is thus possible to construct a refractometer, either for demonstration purposes or for precision work, without the use of high-quality optical components. Even when patent plate glass is used good fringes can be obtained. Jamin–Lebedeff polarizing interference microscopy is a classical method for determining the refractive index and thickness of transparent tissues. Here, we extend the application of this method .

Some aspects of the geometry of the Jamin refractometer . The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science: Vol. 14, No. 95, pp. 1090-1102. (1932).A refractometer is an instrument used to measure the refractive index of solids and liquids. Several types exist, the most common being the Abbe refra. . Jamin refractometer An instrument designed to measure the index of refraction of a gas by the interference patterns formed by two beams, .Hand-held refractometer. A refractometer is a laboratory or field device for the measurement of an index of refraction (refractometry).The index of refraction is calculated from the observed refraction angle using Snell's law.For mixtures, the index of refraction then allows the concentration to be determined using mixing rules such as the Gladstone–Dale relation and . Several instruments [] such as pycnometer, mass spectrometer, Rayleigh refractometer, infra-red spectrometer and Jamin interferometer were described in literature for determining the percentage purity of heavy water with light water as an impurity.The pycnometer works on the principle of measurement of density of heavy water. The density method is .
1. Introduction The measurement of refractive index has been done through the years by means of refractometers like the Abbe, Jamin, Pulfrich, Rayleigh, Hilgen–Chance, and others [1]. Some of them are based on the critical angle method and others on interferometry. Recently a new class of refractometers has appeared. What is a refractometer? A refractometer is a device used to measure the refractive index (n) of a substance.This physical property can be used to make a variety of assessments, such as to determine the purity of a substance (by comparing its n value with a standard value) or to assist in identifying an unknown substance by comparing its n value to .In 1870 Toepler, together with Boltzmann, applied Jamin's interferometric refractometer and extended the visualization to very weak sound waves at the threshold of hearing. Toepler's pioneering schlieren method stimulated Ernst Mach and his team toobjectively investigate the nature of shock waves: they improved Toepler's time delay circuit . How to Use a Refractometer. Using a refractometer involves proper preparation and calibration. Below is a step-by-step guide: Calibrate the Refractometer: Before using, ensure your refractometer is calibrated. Place a few drops of distilled water on the refractometer prism, close the cover plate to spread the water evenly, and adjust to read zero (or the specific .
