Colorimeter-Nephelometer

Greetings, dear readers! Today we want to tell you about such an interesting device as a colorimeter-nephelometer, which is used to determine the concentration of substances in solutions.

A nephelometer colorimeter is a device that allows you to compare the color intensity or light scattering of the test solution and the reference solution. It is widely used in biochemical research where precise determination of the concentration of various substances is required.

The operating principle of a colorimeter-nephelometer is based on the fact that the solution under study is compared with a standard solution, the concentration of which is known. If the concentration of a substance in the test solution is higher than in the reference solution, then the device shows a higher color intensity or stronger light scattering.

There are several types of nephelometer colorimeters, which differ from each other in the way they measure color intensity or light splitting. For example, photometric nephelometer colorimeters use photodiodes or photomultiplier tubes to measure light intensity, while spectrophotometric nephelometer colorimeters can measure light intensity at different wavelengths.

Thus, the colorimeter-nephelometer is an indispensable tool in biochemical and other studies related to determining the concentration of substances in solutions. It provides accurate and reliable results, making it an indispensable instrument for scientific laboratories and manufacturing plants.

**Colorimeters-nephelometers** are devices based on the spectral principle. The set of methods and devices that make it possible to observe the properties of optical radiation is called optics. In addition to working in visible light, optics covers ultraviolet, infrared and other ranges of electromagnetic radiation. The colorimeter serves as a tool for determining various parameters, for example, humidity level, solution concentration, material composition, air pollution, and environmental quality indicators. Therefore, the scope of application of this device is very wide: in medicine, industry and agriculture. However, there is another type of device, which in the scientific community is called a “nephelometer”. The term "colorimetry" comes from the Latin color - color and metron - measure. Translated into Russian, this means “color measurement”, or “color metric”. The essence of the method is to compare the intensity of the studied and control colors.
