X-ray Fluorescence Techniques for Element Abundance Analysis in Wine

The elemental composition has been extensively used to characterize wine and find correlations with environmental winemaking factors. Although X-ray fluorescence (XRF) techniques offer many advantages, they have rarely for analysis. Here, we show the comparison of results obtained by total reflection (TXRF) energy dispersive (EDXRF) elements K, Ca, Mn, Fe, Cu, Zn, Br, Rb, Sr. TXRF EDXRF additionally verified inductively coupled plasma–mass spectrometry. important analytical features XRF in science described, preservation volatile (e.g., Br) being one their main advantages. In addition, shown that an optimal approach building large data sets containing highly reliable reproducible abundances wines, corresponding soils, grape juice. Such are especially geographic authentication wine. This 37 Austrian Croatian wines collected together respective soils from selected regions. element soil reflect a portion juice finished suggesting contribution soil, is, plant uptake capacity expressed as ci(wine)/ci(soil) concentration factors, can be discriminating factor fingerprinting. indeed proved present study discrimination based only on abundances. We identified Sr best discriminator geographical opens new perspective extending application cost-effective tool creating databases juice, evaluation characteristics other parameters composition.
