Helium shortages – how analytical laboratories can prepare for the future
February 2022

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.”

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.
Find out more by downloading our introductory e-book which explains more about the technique and it's place in the analytical laboratory
