Fast wine screening for total content of F-, Cl-, Br- and S-organic compounds

Abstract

Fast direct method for total content determination of heteroelementorganic compounds in dry white wine was developed. The method is based on liquid extraction, removing extraction agent outside the reactor, oxidative high temperature conversion of whole analytes concentrate and analysis of whole absorbate volume of analytes by ion chtomatography. Detection limit of the method was 10-6 – 10-5 g/l (wine volume was 1 ml) and 10-7 – 10-6 g/ml (wine volume was 10 ml) depending on the element. The possibility to identify pesticides applied in wine production, based on registration of heteroelements existing in the molecule, was regarding.Keywords: elemental analysis, wines quality control, pesticides.
Key words: elemental analysis, wines quality control, pesticides.
