Panel discussion – Should I move from helium to hydrogen carrier gas?
Should GC–MS analysts be making the switch to using hydrogen instead? This was the topic of a panel discussion, “Helium shortage 4.0: Is hydrogen carrier gas the solution to the GC–MS problem?” hosted by Separation Science, and held in September 2022. This blog post summarises the topics covered, and shows that there’s a lot to gain by moving to hydrogen.

Assessing low-temperature thermal treatment techniques for PFAS using TD–GC–MS analysis
This on-demand webinar delves into the analysis PFAS – the “forever chemicals” that are known pose an ever-increasing risk in the environment – using automated TD–GC–MS
What is thermal desorption?
Thermal desorption (TD) is a versatile preconcentration technique for gas chromatography, which is used to analyse volatile and semi-volatile organic compounds from solids, liquids or gases.

Using hydrogen as a carrier gas with -xr series thermal desorbers
Markes International’s Multi-Gas enabled thermal desorption (TD) instruments have been selected for the prestigious Innovation Awards from The Analytical Scientist – the world’s first range of TD instruments that are independently safety-certified to run using helium, nitrogen or hydrogen as carrier gas in TD–GC–MS workflows.
“Moving from helium to hydrogen for TD makes economic sense, with helium prices increasing rapidly. Many labs who have become frustrated with helium availability will find this product to their liking.”
