COMPOSITION POUR LA DETECTION OPTIQUE DE PARTICULES, COMPRENANT DE L'EAU, LES PARTICULES, UN SURFACTANT ET UN POLYMERE HYDROPHILE, SYSTEME ET PROCEDE DE DETECTION OPTIQUE ASSOCIES

摘要

A system for detecting optical particles comprises a transparent slide a composition arranged on the slide, a light sourced able to light the composition and the slide, and a device for acquiring at least one image of the composition lit by the light source, the transparent slide being positioned between the light source and the acquisition device. The composition comprises water, the particles, a surfactant and a hydrophilic polymer, the particles having a diameter preferably smaller than 10 μm, still more preferably smaller than 1 μm, the surfactant having a concentration preferably at least equal to the critical micellar concentration, the hydrophilic polymer having a boiling temperature higher than that of water.
