This invention provides an apparatus for measuring a liquid sample, comprising a liquid sample measuring apparatus (110a)for measuring the concentration of a specific component contained in a liquid sample deposited in a spot form on a biosensor (30). A timer (122) for measuring the time taken from the mounting of the biosensor (30) to spotting of the liquid sample onto the biosensor (30) is provided. The measurement result of the concentration of the specific component in the liquid sample spotted onto the biosensor (30) is corrected based on the time measured by the timer (122). The above constitution can improve the measurement accuracy by utilizing a correction algorithm for which the environment temperature and the temperature of the biosensor per se have been taken into consideration.

L'invention concerne un appareil pour mesurer un échantillon liquide, qui comprend un appareil (110a) de mesure d'un échantillon liquide, qui mesure la concentration d'un composant spécifique contenu dans un échantillon liquide placé sous forme de tache sur un biodétecteur (30). Un chronomètre (122) mesure le temps entre le montage du biodétecteur (30) et la formation de la tache de l'échantillon liquide sur le biodétecteur (30). Le résultat de la mesure de la concentration du composant spécifique dans l'échantillon liquide placé sous forme de tache sur le biodétecteur (30) est corrigé en fonction du temps mesuré par le chronomètre (122). L'agencement décrit ci-dessus permet d'améliorer la précision de mesure en utilisant un algorithme de correction qui tient compte de la température ambiante et de la température intrinsèque du biodétecteur.
