Casestudy LGR ICOS wine frauds

ABB LGR Off-Axis ICOS system detects wine frauds.

Wine authentication research is an important topic to avoid wine frauds, which can cause economical damages for the wine producers.

Recently, the University of Groningen in The Netherlands published an article named “ Measurement of δ18O and δ2H of water and ethanol in wine by Off-Axis Integrated Cavity Output Spectroscopy and Isotope Ratio Mass Spectrometry” (Xing Wang · Henk G. Jansen · Haico Duin · Harro A. J. Meijer) in “European Food Research and Technology” magazine

In this study, the ABB-LGR IWA-35EP system Off-Axis Integrated Cavity Output Spectroscopy was used to directly measure the δ18O and δ2H of water in wine samples, without pre-treatment. The results were also compared with the isotope values measured by high-temperature pyrolysis combined with Isotope Ratio Mass Spectrometry (IRMS). The main results’ difference between the two methods is caused by ethanol, so, in principle, we can also obtain δ2H wine ethanol information, thereby avoiding the use of the complicated and not generally available Deuterium-Nuclear Magnetic Resonance (2H-NMR) method. The paper shows the possibilities and limitations of this approach.

The full article can be found here.
