Centri 90
A breakthrough in automated sample preparation, extraction, and concentration for GC–MS. Centri 90 delivers high-sensitivity and high-throughput routine analysis by Headspace, SPME and SPME-Arrow. Using best-in-class robotic automation and back-flushed trap for unattended, rapid and efficient extraction and preconcentration of (S)VOCs. With an option for H2 carrier gas for faster chromatographic speed and lower cost-of-ownership.
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.”
