Abstract
(EN) A densitometer for measuring an objective component with a test piece suitable for the component; a test piece for the densitometer; a biosensor system; and a method for forming a terminal of a test piece. An identifying electrode (104) is provided in addition to an anode (102) and a cathode (103) in order to recognize the type of the attached test piece on the measuring instrument (101) side. Only when a test piece (115) suitable for the instrument is attached, therefore, the instrument can measure the component in a liquid sample by the electrical connection between the identifying electrode and the terminal of the attached test piece. Further, a measuring instrument (251) senses a variation for working curve information selection in order to select the working curve information corresponding to the production lot of the attached test piece to compensate the error of the concentration of the component.
(FR) Densitomètre destiné à mesurer un élément donné à l'aide d'une pièce d'essai adaptée pour ledit élément, pièce d'essai pour ce densitomètre, système de biocapteur et procédé permettant de former une borne d'une pièce d'essai. Une électrode d'identification (104) est fournie en plus d'une anode (102) et d'une cathode (103) pour reconnaître le type de pièce d'essai attachée du côté de l'instrument (101) de mesure. Ce n'est donc que lorsqu'une pièce d'essai (115) adaptée pour l'instrument est attachée que l'instrument peut mesurer le constituant dans un échantillon liquide par connexion électrique entre l'électrode d'identification et la borne de la pièce d'essai attachée. En outre, un instrument (251) de mesure détecte une variation en vue de la sélection d'informations de courbe de travail afin de sélectionner les informations de courbe de travail correspondant au lot de production de la pièce d'essai attachée pour compenser l'erreur de concentration du constituant.
