Title (EN) METHOD AND APPARATUS FOR URINALYSIS, METHOD OF MEASURING OPTICAL ROTATION AND POLARIMETER
(FR) PROCEDE ET APPAREIL D'ANALYSE D'URINE, PROCEDE DE MESURE DE LA ROTATION OPTIQUE ET POLARIMETRE
Abstract:
(EN) An apparatus for urinalysis which requires easy maintenance without using articles of consumption by measuring the optical rotation of urine to determine the concentration of optically active substances in the urine. Polarized light is transmitted through a sample placed in a magnetic field, and a polarimeter detects the change in the direction of polarization of light caused by the effect of the magnetic field. Thus, there are provided a small-sized low-cost reliable apparatus for urinalysis.
(FR) La présente invention concerne un appareil d'analyse d'urine dont l'entretien est facile et qui n'utilise pas d'articles consommables, grâce à la mesure de la rotation optique de l'urine pour y déterminer la concentration de substances optiquement actives. On envoie de la lumière polarisée à travers un échantillon placé dans un champ magnétique, et un polarimètre détecte le changement de direction de la polarisation de la lumière causé par le champ magnétique. Ainsi, on dispose d'un appareil de petites dimensions et peu coûteux pour l'analyse d'urine.
