Semiconductor Lithography Optics (Photolithography) in Hydrogen
Today’s semiconductor manufacturing uses Photolithography in the microfabrication process to pattern parts of a thin film or the bulk of a substrate. It uses extreme ultra violet light to transfer complex geometric patterns from a photomask to a light-sensitive chemical “photoresist” on the substrate. A series of chemical treatments then either engraves the exposure pattern into,…

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 a common commercial use for larger amounts of deuterium. Tritium is produced in nuclear reactors by neutron activation and it…

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 can only detect a few of the required impurities, the gas producer or distributor will need to invest…

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 from internal combustion engine/generator combinations to small scale fuel processors coupled to fuel cells to generate electricity. Power+Energy hydrogen flow…

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. Power+Energy HEMS analyzers detect all impurities up to 100 Atomic Mass Units (AMU) with part-per-billion (ppb) levels…

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 Standards Organization (ISO). Importantly the specification sets upper limits for the critical impurities of sulphur and carbon monoxide. These…
