Förfarande och anordning för bestämning av koncentration av en komponent av dispergerad form i fluidström |
摘要 |
A method and apparatus for determining the concentration of a component present in a fluid stream in dispersed form wherein the following steps are carried out: (a) emitting a light beam in a predetermined range of wavelengths to a fluid sample to be analyzed, said sample flowing through a measurement cell; (b) selecting a number of different wavelengths in said predetermined range; (c) measuring a number of light intensities while sample fluid is flowing through the measurement cell and deriving therefrom a number of measurement sets which each consists of a number of measured light intensities at said different wavelengths; (d) measuring a number of light intensities, while reference fluid is flowing through the measurement cell and deriving therefrom a number of reference fluid measurement sets which each consists of a number of measured reference light intensities at said different wavelengths; (e) deriving from the data, thus obtained, information on the concentration of dispersed components in the fluid stream. |
