Title (EN) THROUGH-CONTAINER OPTICAL EVALUATION SYSTEM
(FR) SYSTÈME D'ÉVALUATION OPTIQUE DANS UN CONTENANT
Abstract:
(EN) An apparatus, and method of its use, to determine a characteristic of a fluid sample contained inside a closed container. The ratio of intensity for detected radiation (e.g., light), subsequent to its transmission through the container's walls and fluid in the container, at each of a reference wavelength and a measurement wavelength is compared to a predetermined value to make a determination of the fluid's characteristic. Desirably, the wavelengths are applied to the same location on the container to minimize a source of signal error. The reference wavelength is selected for its substantial lack of attenuation when transmitted through a known fluid composition. The measurement wavelength is selected for its predictive interaction (e.g., absorption) with the fluid.
(FR) L'invention concerne un appareil, son procédé d'utilisation permettant de déterminer une caractéristique d'un échantillon de fluide contenu dans un contenant fermé. Le rapport d'intensité d'un rayonnement détecté (par exemple, la lumière), suite à sa transmission à travers les parois du contenant et le fluide dans le contenant est comparé, pour chaque longueur d'onde de référence et chaque longueur d'onde mesurée, à une valeur prédéterminée pour établir une détermination de la caractéristique du fluide. De manière souhaitable, les longueurs d'onde sont appliquées au même endroit sur le contenant pour réduire au minimum une source d'erreur de signal. La longueur d'onde de référence est sélectionnée pour son manque d'atténuation substantiel lors d'une transmission à travers une composition de fluide connue. La longueur d'onde mesurée est sélectionnée pour son interaction prédictive (par exemple, l'absorption) avec le fluide.
