Quality and safety testing of foods and beverages

Learn how to overcome common problems associated with sampling volatiles from foods and beverages and how sensitivity can be improved using trap-enabled, extraction and enrichment methods like headspace, SPME, HiSorb high-capacity sorptive extraction and tube-based TD. Explore how automated sample preparation combined with GC×GC–TOF MS can tackle complex samples that are out of reach for traditional GC–MS, and how data handling no longer needs to be the bottleneck of analytical workflows.

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.”
