A nephelometer is an instrument used to measure the concentration of suspended particles in a liquid or gas. It operates on the principle of light scattering. A beam of light is passed through the sample, and the amount of light scattered by the suspended particles is measured at an angle to the incident beam. The intensity of the scattered light is proportional to the concentration and size of the particles.

Nephelometers are commonly used in various fields. In environmental monitoring, they can measure air pollution levels by detecting the concentration of aerosols. In water quality analysis, they are used to determine turbidity, which is a measure of water clarity affected by suspended solids. The medical field also utilizes nephelometers for blood analysis, for example, in measuring protein concentrations or detecting immune complexes.

The calibration of a nephelometer is crucial for accurate measurements. This is typically done using standards of known particle concentrations or turbidity. Different nephelometer designs exist, varying in the wavelength of light used, the scattering angle measured, and the detection method. Despite these variations, the fundamental principle of measuring light scattering remains the same. The sensitivity of a nephelometer allows for the detection of very low concentrations of particulate matter.
