摘要： A system for determining one or more properties of one or more gases. The system comprises sensors configured to measure thermal conductivity and exothermic responses of a sample at multiple temperatures. Sensor responses to exposure to a gas sample at two or more temperatures are compensated and analyzed by a subsystem. The subsystem is configured to determine a thermal conductivity of the gas sample at each of the two or more temperatures and determine at least one component of the gas sample based at least in part on the thermal conductivity value of the sample at each of the two or more temperatures. Related systems and methods of determining one or more properties of a sample are also disclosed.

摘要： A method of calibrating a gas sensor comprises determining a sensitivity of a gas sensor to one or more conditions proximate the gas sensor, determining one or more initial calibration factors comprising a sensitivity of the gas sensor to one or more analytes of interest, determining a current sensitivity of the gas sensor to the one or more conditions proximate the gas sensor by measuring a response of the gas sensor while the one or more conditions proximate the gas sensor varies during operation of the gas sensor, and adjusting the one or more initial calibration factors of the gas sensor based, at least in part on the current sensitivity of the gas sensor to the one or more conditions proximate the gas sensor, and a relationship between the sensitivity of the gas sensor to the one or more analytes of interest to the sensitivity of the gas sensor to the one or more conditions proximate the gas sensor. Related gas detectors, related methods of compensating and calibrating the gas sensors, and methods of determining a functionality of the gas sensors are disclosed.
