The thermal conductivity detector (TCD), also known as a katharometer, is a bulk property detector and a chemical specific detector commonly used in gas chromatography. [1] This detector senses changes in the thermal conductivity of the column eluent and compares it to a reference flow of carrier gas. Since most compounds have a thermal ...
NASA also references Safety Standard for Hydrogen and Hydrogen Systems [110] and the Sourcebook for Hydrogen Applications. [ 111 ] [ 106 ] Another organization responsible for hydrogen safety guidelines is the Compressed Gas Association (CGA) , which has a number of references of their own covering general hydrogen storage, [ 112 ] piping ...
A hydrogen sensor is a gas detector that detects the presence of hydrogen. They contain micro-fabricated point-contact hydrogen sensors and are used to locate hydrogen leaks. They are considered low-cost, compact, durable, and easy to maintain as compared to conventional gas detecting instruments. [1]
Plans to build a controversial hydrogen energy facility have been put on hold after the Health and Safety Executive (HSE) raise concerns. Japanese firm Marubeni Europower wants to create a ...
Recombiners aim at removing hydrogen and thereby preventing explosions. [2] Inside a recombiner there are plates or pellets that are coated with platinum or palladium catalyst. On the surface of the catalyst, hydrogen and oxygen molecules react chemically at low temperature and low hydrogen concentration. The reaction generates steam.

Helium content may also be determined on the basis of measuring the speed of sound in the analyzed gas mixture. [3] The speed of sound depends on the mixture of gases and the temperature of the mix; in the analysis of trimix the speed of sound can be described by a non-linear function of temperature, oxygen content and helium content, and thus the content of helium can be determined by ...
