Carrier Gas Alternatives: Considerations when Switching from Helium

Posted by Teledyne Tekmar on Thu, Sep 13, 2012 @ 04:30 PM

With helium increasing in scarcity and price, many laboratories are looking for cheaper and more readily available alternatives. Some have also been restricted or cut off completely from their suppliers due to the demand. In the realm of gas chromatography, this leaves hydrogen and nitrogen as the most viable alternatives for carrier gas. Gas generators are available from a variety of vendors for both hydrogen and nitrogen. Installation of one of these generators can lead to considerable cost savings over its lifetime, especially when changing from helium gas cylinders. New methods are also starting to allow alternative gases to accommodate these supply challenges.
