Event Overview

Fluctuating global helium levels are causing problems, such as difficulty sourcing helium and increasing costs, for the many industries that rely on it. Currently, this is having a serious effect on gas chromatography–mass spectrometry users, who use helium as a carrier gas, in many parts of the world. One solution to this problem is switching to an alternative carrier gas.

Alternative carrier gases (nitrogen and hydrogen) are more readily available than helium and can be used with gas chromatographs. However, there has been a barrier to their use in some analytical processes. Thermal desorption instruments, which preconcentrate samples down to a volume that is suitable for injection into the narrow gas chromatograph column, have only been able to run with helium or nitrogen as the carrier gas, but nitrogen is much less efficient than helium. Mass spectrometers have the same issue.

To combat these issues, manufacturers of thermal desorption and mass spectrometry instruments are upgrading to multi-gas systems, which enable analysts to switch between three gases – helium, nitrogen and hydrogen.

In this on-demand presentation and discussion forum, our panel of experts talk about the pros and cons of using hydrogen as an alternative carrier gas and address audience questions.
