Abstract: A system is presented. The system includes an absorption cell filled-with a gas-mixture, a mirror-cum-window comprising a first portion that acts as a first mirror and a second portion that acts as a first window, a second mirror, a plurality of radiation sources to generate a plurality of light beams directed into the absorption cell through the first window followed by reflection of the plurality of light beams between the first mirror and the second mirror to irradiate the gas-mixture resulting in generation of a plurality of transmitted light beams passing out of the absorption cell through the second window, a detector that detects at least one characteristic of the plurality of transmitted light beams resulting in generation of one or more response signals, and a processing subsystem that analyzes the gas-mixture at least based on the one or more response signals.

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.
