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.

Multi-mode extraction & enrichment platform
Powered by best-in-class robotic automation, and using a modular design, Centri® gives unrivalled flexibility for unattended, rapid and efficient extraction and enrichment of VOCs and SVOCs. With its four sampling modes, Centri offers maximum versatility for liquid, solid and gaseous samples.

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.
