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

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.”
Ethylene oxide analysis
In 2020, concerns over levels of the carcinogen ethylene oxide found in sesame seeds from India were raised in Belgium. Since then, monitoring ethylene oxide in foods has become vital. Now, thousands of food items with a long shelf-life, such as cereals, chocolate, biscuits, bread, crackers, spices and bagels, are under investigation.
We discuss:
(1) Why is ethylene oxide used in foods?
(2) Why is ethylene oxide unsafe for humans?
(3) Using Centri® for the analysis of ethylene oxide
