Abstract
Systems, devices, and methods are provided for detecting and measuring the concentration of non-reactive gases in a given environment, without having to increase the reactivity of the non-reactive gases through thermal heating. For example, a gas sensor device includes a sensing chamber, a chemical getter element disposed in the sensing chamber, and a pressure sensor device. The sensing chamber is configured to capture a gas sample. The chemical getter element is configured to remove reactive gas species of the gas sample through chemical reaction of the reactive gas species with the chemical getter element at room temperature. The pressure sensor device is configured to measure a pressure of non-reactive gas species of the gas sample, which remains in the sensing chamber after removal of the reactive gas species from the sensing chamber. The pressure measurement is used to determine an amount of the non-reactive gas species present in the sample.
