Kemisk analys som utnyttjar det fenomen att ljus, som passerar ett medium med finfördelade partiklar med annat brytningsindex än mediet självt, minskar i intensitet genom spridning. I turbidimetri mäts intensiteten hos ljus som passerat genom mediet utan spridning. I nefelometri mäts intensiteten hos det spridda ljuset, vanligtvis, men inte nödvändigtvis, i räta vinklar mot den infallande ljusstrålen.
Chemical analysis based on the phenomenon whereby light, passing through a medium with dispersed particles of a different refractive index from that of the medium, is attenuated in intensity by scattering. In turbidimetry, the intensity of light transmitted through the medium, the unscattered light, is measured. In nephelometry, the intensity of the scattered light is measured, usually, but not necessarily, at right angles to the incident light beam.
