Multi-Gas enabled technology for -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.

Tackling food fraud in the olive oil industry
How do you tell a genuine olive oil from a counterfeit product? Professor Giorgia Purcaro at the University of Liège is addressing this question by profiling its headspace volatiles, which offers better reproducibility than conventional assessments using trained sensory panels. With sensitivity crucial to success of this approach, Professor Purcaro has turned to headspace-SPME on Markes’ Centri platform to identify marker compounds that distinguish genuine oils from fraudulent equivalents – with very encouraging results.
