A nephelometer [1] or aerosol photometer [2] is an instrument for measuring the concentration of suspended particulates in a liquid or gas colloid. A nephelometer measures suspended particulates by employing a light beam (source beam) and a light detector set to one side (often 90°) of the source beam.
the nephelometer: an instrument for estimating the number of bacteria in suspensions used for calculating the opsonic index and for vaccines. joseph mcfarland, m.d. jama. 1907; xlix(14):1176-1178.
Nephelometry is a technique used in immunology to determine the levels of several blood plasma proteins. For example, the total levels of antibodies isotypes or classes: Immunoglobulin M, Immunoglobulin G, and Immunoglobulin A. [1]
The propensity of particles to scatter a light beam focused on them is now considered a more meaningful measure of turbidity in water. Turbidity measured this way uses an instrument called a nephelometer with the detector set up to the side of the light beam. More light reaches the detector if there are many small particles scattering the ...
