Scarce and costly helium supplies are forcing changes and new choices
A few words about the helium vs. hydrogen crisis, and how Overbrook Support can help
There was a time, just a few years ago, when helium was in abundant supply and was the preferred choice as a carrier gas in GC and GC/MS. Those days may be over.
Helium Supplies Are Scant, Again, headline news at C&EN, July 16, 2012 (C&EN). Prices are rising – from $5.00 per L in 2008 to $15 today, making recycling worth consideration. Or switching to hydrogen.
In Considerations on Switching from Helium to Hydrogen, by Reginald J. Bartram and Peter Froehlich, in LCGC (Vol. 28, #1 Oct 2010), the authors spell out the facts to a very real crisis. .At one time, helium was preferred as a carrier gas because it provides good separations, is inert and safe to use, and was in ample supply. But a new reality is at hand they say.
The cost of helium has nearly tripled, while supplies are limited. Hydrogen as your carrier gas actually
No wonder, every week now, progressive labs are switching from helium to hydrogen as their carrier gas.
What can you do about it?
For a limited time, Overbrook Support Services will arrange for a specialist to meet with you at no charge to conduct a gas audit.
Labs are adopting hydrogen because its advantages are well-documented as evident by the van Deemter curve (right):
Hydrogen is a superior carrier gas
Brand new hydrogen generators are available too for your lab.
