Dioxin testing will soon be five times more sensitive
Stringent dioxin regulations are causing quite a buzz in the European reference lab network
Some of the world's leading research into dioxin analysis is happening at the University of Liège Faculty of Sciences, where Chemistry department head Jean-François Focant and his team are spearheading studies on dioxin testing using triple quad GC-MS. This method will enable labs to meet the stricter analytical standards the EU is set to impose.
Triple quad GC-MS is used more and more to replace magnetic sector-mass spectrometry, which was the only authorized method for dioxin determinations until about five years ago. Even Focant's lab still uses these enormous machines. Their performance is excellent, but analysts need specialist knowledge to use them and they have a huge footprint. By contrast, a triple quad-mass spectrometer fits on a lab bench, costs half, is more user-friendly, and works just as well as magnetic sector MS. Focant’s research group has been working on triple quad analytical methods for years.
