PHOTOMETRIC ANALYSER FOR STUDYING AUTOMATICALLY COMPLEX SOLUTIONS

摘要

ABSTRACT OF THE DISCLOSUREThe present invention relates to a photo-metric measuring device making it possible to auto-matically study complex solutions with variable"background noise"; the device comprises a light sourcemaking it possible to illuminate a measuring cell,plates for splitting the light beam from the sourceinto a plurality of individual beams, balancing systems,interference filters for selecting each wavelength asso-ciated with each of the light beams, a discriminatormaking it possible to distinguish the different wave-lengths, monochrometors for making the light beamsmonochromatic, a detection element and an analog com-puting system making it possible to calculate the con-centration of several dissolved chemical species.
