The Basic Principle Of The Refractometer

- Oct 25, 2017 -

Based on the principle that the refractive index of sugar solution is proportional to the concentration principle, the sugar refractometer can be used to directly determine the sugar content in sugar containing solution. As long as the detecting prism lens can add 2-3 drops of solution. Sugar refractometer for rapid determination of sugar solution solubility, wine density; can also measure other non sugar solubility or refractive index through the conversion, is a essential instrument of sugar, wine, food and beverage, agricultural research, textile and mining machinery and other industries.

The theory of refraction refractometer

If you put a pencil in a glass of water, the top will be curved. Then if you're in a cup of sugar and placed the same experiment, the pencil top should be even more curved. An example of this phenomenon of refractive index.

Due to the adoption of new refractometer optical system into a practical use. To measure the solubility of solution through the conversion relationship between the refractive index of the solution and the solubility of the material. When the density increased (for example. When the sugar in water solubility is when dissolved substances increase), the refractive index of lead proportionately increased.

1. by prism refraction test than the refractometer hold high rate theory; to measure the solution solubility or refractive index by means of conversion.

2. in the case of the weak solution, the solution refractive index than the prism, so the refraction angle is relatively large.

3. in solution was relatively strong when the solution refractive index than the prism is low, so the angle of refraction is relatively small.
