Title
(EN) CALIBRATOR FOR A SENSOR
(FR) CALIBREUR POUR CAPTEUR
Abstract
(EN)
A calibrator, for calibrating a sensor, has a calibration chamber for containing a calibration liquid. The liquid comprises water or an aqueous solution of an analyte to be sensed. A hydrogen peroxide-quenching material is provided exposed to the interior of the calibration chamber. The hydrogen peroxide-quenching material contacts the calibration liquid. After the calibration chamber containing the calibration liquid is sterilized by irradiation with gamma radiation, the hydrogen peroxide-quenching material decomposes any hydrogen peroxide formed in the calibration liquid to avoid adverse effects on a sensor placed in contact with the calibration liquid.

La présente invention concerne un calibreur, pour étalonner un capteur, qui a une chambre d'étalonnage destinée à contenir un liquide d'étalonnage. Le liquide comprend de l'eau ou une solution aqueuse d'un analyte à détecter. Un matériau d'extinction à base de peroxyde d'hydrogène est fourni, exposé à l'intérieur de la chambre d'étalonnage. Le matériau d'extinction à base de peroxyde d'hydrogène est en contact avec le liquide d'étalonnage. Après la stérilisation de la chambre d'étalonnage contenant le liquide d'étalonnage par irradiation de rayons gamma, le matériau d'extinction à base de peroxyde d'hydrogène décompose tout peroxyde d'hydrogène formé dans le liquide d'étalonnage pour éviter les effets indésirables sur un capteur placé en contact avec le liquide d'étalonnage.
