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.
