Advanced GC-MS method for quality and safety control of alcoholic beverages

Popis výsledku v původním jazyce

Recently developed and validated simple and reliable quantitative method employing ethanol as an internal standard for GC-MS quantification of volatile compounds in alcoholic products was applied to 36 samples including commercially available worldfamous brand spirits from 18 countries and homemade distillates. The GC-MS analyses were performed simultaneously by the suggested approach and official internal standard method that is prescribed in the legislation of EU and USA. The independent samples t-test was employed to evaluate the statistical difference of results of these two methods. The test revealed no difference in the results and their repeatability. The main benefits of the suggested method are the elimination of the necessity of manual internal standard addition and samples density measurement thus making it more economical and productive.
