Abstract
(EN) A method for using a chemical capture system with integrated calibration (S) comprising a chamber (4) which comprises an opening (40, 41) and a closing member (42), as well as a chemical sensor (1) to be calibrated and a photoionisation sensor (2) which are positioned in the chamber (4), in which method: - during a measurement step, the sensor (1) to be calibrated and the photoionisation sensor (2) measure the gas mixture (6) present in the chamber (4), defining an open interior space (V), so as to identify the gas mixture (6) and - during a calibration step, the photoionisation sensor (2) generates ozone by photoionising the dioxygen in the chamber (4), defining a closed interior space (V) free of gas mixture (6), and the sensor (1) to be calibrated measures the generated ozone, the difference between said measurement and a reference measurement making it possible to calibrate said sensor.
(FR) Un procédé d'utilisation d'un système de captation chimique à étalonnage intégré (S) comprenant une chambre (4) comprenant une ouverture (40, 41) et un organe de fermeture (42), ainsi qu'un capteur chimique à étalonner (1) et un capteur à photoionisation (2) positionnés dans la chambre (4), procédé dans lequel : - lors d'une étape de mesure, le capteur à étalonner (1) et le capteur à photoionisation (2) mesurent le mélange gazeux (6) présent dans la chambre (4), délimitant un volume intérieur (V) ouvert, afin d'identifier le mélange gazeux (6) et - lors d'une étape d'étalonnage, le capteur à photoionisation (2) génère de l'ozone par photoionisation du dioxygène dans la chambre (4), délimitant un volume intérieur (V) fermé exempt de mélange gazeux (6), et le capteur à étalonner (1) mesure l'ozone généré, l'écart de cette mesure avec une référence permettant son étalonnage.
