Abstract: A gas analysis system and method filter different wavelengths of incident light using a variable light filter at different locations along a length of the variable light filter to form filtered light. The variable light filter is configured to be disposed between a light source generating plural different wavelengths of the incident light and a gas sample. Intensities of wavelengths of the filtered light are determined after the incident light generated by the light source passes through the variable light filter and the gas sample. The gas sample may be identified from among different potential gasses based on the intensity of the one or more wavelengths of the filtered light that is determined by the light detector.

Abstract: There are provided methods and devices for sensing hydrogen gas. For example, there is provided a method that includes drawing a sample into a channel. The method includes passing the sample over a collection plate to remove an extraneous gas in the sample, thus yielding a purified sample. The method further includes passing the purified sample on a sensing plate and measuring a concentration of hydrogen in the purified sample using the sensing plate. The measuring can include heating the sensing plate and correlating a change in resistance of the sensing plate with a specified concentration of hydrogen. Furthermore, the method can include regenerating the collection plate following the measuring.
