    Greg Glatzmaier, at the National Renewable Energy Laboratory, determines the high-temperature thermal and mechanical stability of sealants used in a lab prototype of the integrated hydrogen sensor separator module. A hydrogen sensor is a gas detector that detects the presence of hydrogen. They contain micro-fabricated point-contact hydrogen ...

    The Dynamic Albedo of Neutrons (DAN) instrument is an experiment mounted on the Mars Science Laboratory 's Curiosity rover. It is a pulsed sealed-tube neutron source and detector used to measure hydrogen or ice and water at or near the Martian surface. [1] [2] The instrument consists of the detector element (DE) and a 14.1 MeV pulsing neutron ...

    en.wikipedia.org/wiki/Hydrogen_leak_testing

    Hydrogen leak testing is the normal way in which a hydrogen pressure vessel or installation is checked for leaks or flaws. This usually involves charging hydrogen as a tracer gas into the device undergoing testing, with any leaking gas detected by hydrogen sensors. [1] Various test mechanisms have been devised.

    MOS sensors can detect different gases, such as carbon monoxide, sulfur dioxide, hydrogen sulfide, and ammonia. Since the 1990s, MOS sensors have become important environmental gas detectors. [3] MOS sensors although very versatile, suffer from the problem of cross sensitivity with humidity and other gases.
