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 .
The Abbe refractometer is the standard instrument for measuring refractive index of rigid lens materials. This instrument determines the critical incidence angle of a light beam to achieve total internal reflection. . Solution. From Eq. (17.59), 2dcos . which is weight of sugar solids per weight of syrup, and in the laboratory is measured .
When a sugar solution is measured by refractometer or densitometer, the R.I. or °Bx value only represents the amount of dry solids dissolved in the sample if the dry solids are exclusively sucrose. This is seldom the case. Grape juice, for example, contains little sucrose but does contain glucose, fructose, acids and other
Usually refractometers / brix meters are adjusted with water at a specific measuring temperature. This temperature is controlled with a Peltier element, which can cool down or heat up the measuring cell to a specific temperature (e.g. 20°C). Sometimes, Brix standards are used to adjust a refractometer for the measurement of sugar concentrations.However, a refractometer is not very good for measuring multi-component solutions such as water, sugar, and alcohol. When there are several different components in a solution, such as water, sugar, and alcohol, it is difficult to tell what the contribution is that each component makes to the total refractive index.The HI96801 portable refractometer converts the refractive index of a food sample to % brix. This conversion is based on the tables found in the ICUMSA Methods Book (International Commission for Uniform Methods of Sugar .Table 1.—Conversion of Scale Readings, B & L Precision Sugar Refractometer, on Normal Weight Sugar Solutions at 20° C into Brix of Solution and Brix of Original Product. —Prism Series 716.
