Tritium Separation at Nuclear Plants
Tritium Separation at Nuclear Plants Nuclear power plants use or produce hydrogen isotopes deuterium and tritium. Deuterium is used in heavy water moderated fission reactors, usually as liquid D2O, to slow neutrons without high neutron absorption of ordinary hydrogen. This is...
Hydrogen Production Certification
Hydrogen Production Certification Suppliers of high purity hydrogen generally provide a certificate of analysis (CoA) with each shipment. A CoA will typically call out several impurities, eg. O2, H2O, N2, CO, CO2, CH4 , etc . As most analytical instruments...
Fuel Cell Auxiliary Power Units
Fuel Cell Auxiliary Power Units From cell phone towers to temporary lighting to on-vehicle electronics, the need for reliable, efficient and low noise back-up electrical power generation is growing rapidly. Leading-edge players such as the US Navy are turning away...
Polysilicon Manufacturing
Polysilicon Manufacturing Hydrogen is used in the production of polysilicon manufactured in fluidized bed reactors (FBR) from silane (SiH4) gas. In order to meet the purity requirements of the solar industry, polysilicon manufacturers must use ultra-pure starting materials including Hydrogen....
SAE J2719 Hydrogen Analyzer
SAE J2719 Hydrogen Analyzer The Society of Automotive Engineers (SAE) has developed a specification for hydrogen intended for use in a PEM fuel cell in a motor vehicle, SAE J2719. This same specification has been adopted internationally by the International...
Power Semiconductor Device Manufacturing
Power Semiconductor Device Manufacturing High-purity Hydrogen is used as a carrier gas to transport metal organic source chemicals into the MOCVD reaction chamber. Power devices are either Gallium Nitride (GaN) or Silicon Carbide (SiC) devices. The performance of GaN devices vary...
