摘要：

The parameters of the process of isolation, concentration, and gas chromatographic analysis of volatile organic compounds by solid-phase microextraction were optimized. With different amounts of a mixture of essential oils, the conditions of reproducibility of their determination were established based on the absolute values of the squares of chromatographic peaks obtained by capillary gas chromatography. It was found that the efficiency of the extraction of volatile compounds from gas phase by sorption on mixed polymer (consisting of polydimethylsiloxane and divinylbenzene) was significantly influenced by the structure of their molecules, while the sorption time and their content in the liquid phase influenced the significance of determination.
