Can Hydrogen gas generators replace Helium for Gas Chromatography? (May 2024)

To address the Helium shortage GC laboratories have begun looking at possible replacement gases and new approaches to help obtain the carrier gases needed to continue their work. One of the most promising options is using the use of gas generators to provide a steady supply of hydrogen gas as a replacement for helium. Although some concerns—and some myths—persist about using hydrogen, it offers multiple benefits and advantages over helium, notably particularly when a gas generator replaces high-pressure gas cylinders.
