Chromatographs Configured to Safely and Reliably Utilise Hydrogen in Place of Helium
Recently at the Pittsburgh Conference 2013, Bruker announced their new configurations for the SCION 436 and SCION 456 gas chromatographs supporting the use of hydrogen carrier gas. The continued instability in supply and rising cost of helium has renewed interest and use of hydrogen as the carrier gas for capillary GC applications. Bruker has answered the concerns and calls for help from its customer base to deal with this disruption and significant increase in cost, by delivering GC systems capable of utilising hydrogen safely with no impact on data quality or system robustness.
“While using hydrogen as a carrier gas is not new to gas chromatographers, the safer choice of helium has prevailed,” commented Hans van den Heuvel, GC Product Manager. “However, as we saw the supply problem intensifying and cost for helium rising, we knew we needed to step in and provide a safe, reliable, and easy alternative for our customers. Today we launch SCION GC packages that fully support hydrogen as a carrier gas”.
Hydrogen has been used as an alternative to helium, where users are looking for the benefit of increased column flow and reduced analysis time – without a reduction in separation efficiency. This is clearly another driving factor in users’ desire to switch from helium to hydrogen. “Our customers are looking at hydrogen carrier again as they see benefits from reduced analysis time and now lower operating costs. In some regions customers are reporting helium prices increasing as much as 200 percent, while supply reliability decreases substantially” noted Meredith Conoley, Marketing Director for Bruker CAM.
The SCION GC systems have been certified for use with hydrogen carrier by a third-party certification agency. Special firmware, software and hydrogen sensors allow laboratories to confidently operate these systems with hydrogen carrier gas.

New Precision Gas Generators for GC Instruments
Leading the way in gas generation for over a decade, Peak Scientific have expertly designed a new system solution that can be tailored to any GC laboratory’s needs.
The Peak Precision Series is a modular designed gas generator system that allows you to separate and analyse multiple gas types and complex mixtures with the utmost accuracy in the most spatially economic labs.
We understand the needs of laboratories and the people who work in them. The lab is a unique environment demanding precision, accuracy, reliability and design steeped in functionality.
The Precision Series incorporates a space saving stackable design allowing you to make the most of your lab space. Additionally the modular design allows for different combinations to suit single GC and multiple GC applications.
It also eliminates the inconvenience of gas cylinders, no more changing over, no more supply issues, no safety worries. As a result the range is very low maintenance and provides long term cost stability.
More often than not, which generator model we recommend comes down to the ‘limit of detection’ you are looking for in your GC results. The lower the limit of detection, the purer the gases need to be as you will be looking for the lowest possible baseline to achieve the most precise results. This is why Peak Scientific offers a Standard Analysis Gas Generator Solution as well as a Trace Analysis Gas Generator Solution.
