Abstract

Un procédé et un appareil permettant de mesurer la concentration d'un produit d'analyse présent dans un fluide biologique. Le procédé consiste à envoyer un rayonnement dans le proche infrarouge sur des échantillons d'étalonnage pour obtenir des données d'étalonnage, à analyser ces données pour identifier et éliminer des valeurs aberrantes, à construire un modèle d'étalonnage, à collecter et analyser des échantillons inconnus pour en identifier et éliminer les valeurs aberrantes, et à prévoir la concentration de valeurs aberrantes dans le produit d'analyse à partir du modèle d'étalonnage. L'analyse des données d'étalonnage comprend le prétraitement des données, la décomposition des données pour éliminer celles qui sont redondantes, et l'identification et l'élimination des valeurs aberrantes à l'aide de distances généralisées. L'appareil (100) comprend une pompe (102) qui fait circuler un échantillon dans des conduites (104) pour remplir une cuve à circulation (106). La lumière provenant d'une source de proche infrarouge (114) est synchronisée avec un détecteur (110) ce qui facilite des mesures à la lumière et dans l'obscurité, puis elle traverse un monochromètre (120) et la cuve à circulation (106) et vient frapper le détecteur (110), ce qui permet de mesurer le rayonnement traversant l'échantillon.
