Abstract: An automatic spectrophotometric absorption analyzer for continuous determination of a plurality of components of a fluid sample, comprising a monochromator with a diffraction grating receiving the light transmitted by a vessel with transparent faces which contains said sample, a photoelectric converter so arranged that the light beam emerging from the monochromator falls on its sensitive element, a unit for determining cyclically a plurality of stop positions of said diffraction grating which define wavelengths corresponding to the absorption lines of components of said sample, and means for automatic computation of the concentration of said components from the signal which is delivered by the converter.
