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.
Worldwide helium demand far exceeds current production levels. For many gas chromatography applications, the switch to hydrogen is painless. What’s stopping you?
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.
The majority of laboratories worldwide use gas cylinders to supply their analytical instruments, sample prep systems and other lab applications.
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.
