Disclosed is a method for calibrating a sensor to be calibrated by means of a reference sensor, the sensor to be calibrated being configured to determine a chemical signal based on a conversion function for converting an electrical signal, the reference sensor being configured to determine a reference signal, the method having: ⋅ measuring, during a reference time period, a first chemical signal (SP) and a first reference signal (SP) and, during a test period, a second chemical signal (SP) and a second reference signal (SP), ⋅ determining regression functions (gP, gP) defined as follows: SP=gP(SP) and SP=gP(SP), ⋅ calculating a difference between the regression functions (gP, gP) and ⋅ when the difference is greater than a reference difference, determining an optimized conversion function.

Method and system for calibrating a non-selective chemical sensor

A method for using a chemical capture system with integrated calibration having a chamber which comprises an opening and a closing member, as well as a chemical sensor to be calibrated and a photoionization sensor which are positioned in the chamber, in which method: —during a measurement step, the sensor to be calibrated and the photoionization sensor measure the gas mixture present in the chamber, defining an open interior space, so as to identify the gas mixture and—during a calibration step, the photoionization sensor generates ozone by photoionizing the dioxygen in the chamber, defining a closed interior space free of gas mixture, and the sensor to be calibrated measures the generated ozone, the difference between said measurement and a reference measurement making it possible to calibrate said sensor.
