Sažetak
In this paper the application of HR-ICP-MS for determination of trace elements (Al, As, Ba, Be, Bi, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sb, Se, Sn, Sr, Ti, Tl, U, V and Zn) in wine is presented. We investigated the advantages of using HR-ICP-MS in terms of resolving spectral interferences in complex wine matrices and optimized the analytical method to account for non-spectral interferences caused by presence of nitric acid and ethanol. In addition, we compared quantitative and semi-quantitative modes of analysis for determination of trace elements in diluted wine samples high resolution inductively coupled plasma mass spectrometry (HR-ICP-MS). Tenfold dilution of wine samples, with In used as single internal standard, and quantification based on matrix-matched calibration standards was found to be the best choice in terms of achieved sensitivity and elimination of possible spectral and non-spectral interferences. No significant differences were observed between white and red wines based on recovery percentages, accuracy and precision. Quantitative and semi-quantitative modes of analysis gave comparable results in terms of LOD values, precision (RSD < 5 %) and accuracy (differences < 20 %) in both red and white wine. These results indicate that both quantitative and semi-quantitative modes of analysis are applicable for the trace element determination of wines with HR-ICP-MS.
