ABSTRACT:
The present invention relates to a photometric measuring device making it possible to automatically study complex solutions with variable "background noise."
This device comprises a light source (2) making it possible to illuminate a measuring cell, means for splitting the light beam (20, 22) from source (2) into a plurality of individual beams, balancing means (24), means (26) for selecting each wavelength associated with each of the light beams, a discriminator (28) making it possible to distinguish the different wavelengths, means (26) for making the light beams monochromatic, detection means (46) and an analog computing system (44) making it possible to calculate the concentration of several dissolved chemical species.
Application to the following or monitoring of chemical reactions.
