Articles and Applications
Helium is the second most abundant element in the universe, but on Earth it’s relatively rare, found trapped underground with natural gas and in the atmosphere, where it escapes into space.
The aim within the laboratory should be to achieve the best separation in the shortest time period. The most commonly used gases as carrier gas for GC are nitrogen, hydrogen and helium.
Many laboratories are now prohibited from placing Hydrogen cylinders on their premises owing to health and safety restrictions. A Peak Scientific Precision Hydrogen Trace generator is a safe alternative to gas cylinders whilst providing pure carrier gas (99.9999% purity, moisture free), in quantities great enough to supply a number of GCs simultaneously.
Technology Considerations on Hydrogen Generation Technology Hydrogen Generators that are utilised to provide Carrier Gas for GC and GC/MS applications employ many technologies to provide high purity hydrogen. Here were look at the various methods used to purify hydrogen. Three using PEM (Proton Exchange Membrane), combined with various purification techniques, and the fourth using a combined Palladium Electrolyser.
Several technologies are available for generating high-purity hydrogen, but palladium diffusers offer many advantages over the others.
