Direct Thermal Extraction Analysis Using GERSTEL Platform

This technical report details the application of direct thermal extraction (DTE) for analyzing volatile and semi-volatile compounds in solid and liquid samples using the GERSTEL Universal Platform. The study specifically investigates the extraction of aroma compounds from three brands of pumpkin spice scented wax candles. The methodology involves minimal sample preparation, where scented wax samples are heated in a thermal desorption unit under inert gas flow to release volatile compounds. The report outlines the experimental setup, including the use of Tenax TA sorbent tubes for air sampling and the subsequent analysis via gas chromatography-mass spectrometry (GC/MS). Results indicate varying concentrations of key fragrance compounds such as limonene, linalool, and eugenol across the different candle brands. The findings highlight the importance of monitoring these compounds for quality control and consumer acceptance. The report concludes with a discussion of the chromatographic results and their implications for product quality assessment.
