[主題詞] Nephelometry and Turbidimetry
[英文釋義] 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.
