Title of the thesis:Use of Multicolumn Setups in Gas Chromatography of Selected Volatile Constituents of Food
Summary:Multidimensional chromatography used orthogonally coupled multiple columns with different stationary phases. The experiment involves transferring the fractions from the first chromatographic column to the secondary (or additional) chromatographic column/columns for additional separation. Multidimensional chromatography allows separation of complex mixtures that cannot be separated using a single column. The most popular version of multidimensional chromatography is two-dimensional chromatography GC×GC, which can be used in areas such as food, environmental, biological and petrochemical analysis. The aim of this project was to review the literature on comprehensive two-dimensional gas chromatography (GC×GC), with emphasis on application in the analysis of fruit juice samples. Various strategies that can be used in these studies, the present state of analytical performance and the potential of GC×GC combined with mass spectrometry are discussed to achieve the aims of the project. The results show that GC×GC can be applied to analyze beverage samples in order to determine trace-level constituents or contaminants, or to solve their composition.
Key words:multidimensional chromatography, two-dimensional gas chromatography, food analysis
