摘要：A method and apparatus for determining the concentration of a componentpresent 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 beanalyzed, said sample flowing through a measurement cell; (b) selecting a number ofdifferent wavelengths in said predetermined range; (c) measuring a number of lightintensities while sample fluid is flowing through the measurement cell and derivingtherefrom a number of measurement sets which each consists of a number of measuredlight intensities at said different wavelengths; (d) measuring a number of light intensities,while reference fluid is flowing through the measurement cell and deriving therefrom anumber of reference fluid measurement sets which each consists of a number ofmeasured reference light intensities at said different wavelengths; (e) deriving from thedata, thus obtained, information on the concentration of dispersed components in the

fluid stream.
