Spectral analyzer of light absorption of a solution

摘要

P the invention relates to a spectral analyzer of light absorption of a solution. / p & & p & this analyzer comprises a transparent vessel containing the solution was analyzed, a light source, means for dividing the beam of the source in a measuring beam passing through the tank and a reference beam passing through the absorber reference. The means make it possible to modulate these beams. This analyzer is characterizes in that the modulation means are located immediately behind the vessel, on the path of the measuring beam and immediately behind the absorber, on the path of the beam of reference, the means for dividing the beam of the source being disposed in the manner to converge the measurement beam on the vessel. / p & & p & application to the optical analysis of solutions and in particular to the metering simultaneous of two compounds dissolved in a solvent such as the blood. / p
