AppNote 256: A Comparison of 4 GC-MS Extraction Techniques to Determine Comprehensive VOC and Semi-VOC Profiles in Fragrance, Beverage, and Building Products
Thoroughly determining the VOCs and semi-VOCs in various consumer goods using the proper extraction technique for GC-MS is vital for ensuring quality control, batch consistency, regulatory compliance, and successful product development studies. However, conventional sample extraction methods face significant limitations such as the introduction of additional solvents, the inability to handle matrix complexity, and difficulty achieving extremely low detection limits. In this study, solid phase microextraction (SPME), SPME Arrow, thin film solid phase microextraction (TF-SPME), stir bar sorptive extraction (SBSE/GERSTEL Twister®), and dynamic headspace (DHS) were compared and evaluated to determine which extraction technique produced the best comprehensive chromatographic profiles for three different sample types. It will be shown that the DHS extraction technique offers the most efficient extraction, providing the most analyte mass on column, resulting in very comprehensive chromatographic profiles and very low detection limits.
