Gas Generators
As the ongoing search for helium continues worldwide, the community of analytical chemists often finds itself entangled in the debate of helium versus hydrogen in the field of gas chromatography
Until now helium has never been found intentionally—being accidentally discovered in small quantities during oil and gas drilling
Faced with rising delivery and rental costs and the inconvenience of relying on tanks, many labs today generate their own nitrogen
The Proton OnSite line of hydrogen generators is the simpler, more cost-effective, and less complex approach to supplying hydrogen for laboratory and scientific applications.
Due to the rising costs of storage and the safety risks inherent to using gas cylinders, many labs are switching to gas generators.
As the most abundant element in the universe, hydrogen might seem easy to come by, except that it’s usually bonded to oxygen in water or bound in organic compounds. Many applications, though, require pure hydrogen.
Clinical laboratories have among the most stringent requirements for purity of input materials (reagents, solvents, assay kits, gases, etc.). Yet the Clinical Laboratory Improvement Amendments of 1988 (CLIA), officially promulgated in 1992, leave to clinical and diagnostic laboratory managers the task of assuring the quality and performance of chemicals and gases used to calibrate instruments and conduct general lab operations.
Researchers at the US Department of Energy’s (DOE) Argonne National Laboratory have created a small scale “hydrogen generator” that uses light and a two-dimensional graphene platform to boost production of the hard-to-make element.

For David Hemmig, director of equipment sales at Matheson Tri-Gas (Basking Ridge, NJ), the key word in on-site gas generation is reliability. He explains that a major problem with gas generators that incorporate some sort of compressor is that eventually that component fails.
Problem: In almost any laboratory or scientific research facility today, there are numerous devices, instruments or processes that require cryogenic fluids or gases supplied from cryogenic sources. The past quarter-century has seen cryogenic liquid cylinders expand from a rarity in laboratories with relatively few applications, to become the dominant mode of supplying high-purity gas and cryogenic fluids.
