Nephelometrisellä

Nephelometrisellä is a Finnish term that translates to "nephelometric" in English. It refers to a method of quantitative analysis used in chemistry and physics to measure the turbidity or haze of a liquid sample. This technique relies on the principle of light scattering. When a beam of light passes through a liquid containing suspended particles, the light is scattered in various directions. A nephelometer, the instrument used for this measurement, detects and quantifies the amount of scattered light. The intensity of the scattered light is directly proportional to the concentration and size of the suspended particles in the liquid.

Nephelometric measurements are widely employed in diverse fields. In environmental science, they are used to assess water quality, such as determining the amount of suspended solids in rivers, lakes, and wastewater. In medicine and biology, nephelometry is utilized for quantifying proteins, antigens, and antibodies in biological fluids like blood and serum, aiding in disease diagnosis and monitoring. The pharmaceutical industry uses this method to check the clarity of drug solutions and to monitor particle size in suspensions. The principle behind nephelometry is fundamental to understanding the optical properties of colloidal systems and is a valuable tool for analyzing the composition and characteristics of liquids containing particulate matter.
