AppNote 219: Comparison of Three Types of Thin Film-Solid Phase Microextraction Phases for Beverage Extractions


In this study, Thin Film Solid Phase Micro-Extraction (TF-SPME) devices with carboxen/polydimethylsiloxane (CAR/PDMS), divinylbenzene/ polydimethylsiloxane (DVB/PDMS), and hydrophilic lipophilic balanced/polydimethylsiloxane (HLB/PDMS) coatings are investigated for their usefulness for beverage analysis in combination with Stir Bar Sorptive Extraction (SBSE) using the GERSTEL Twister®. A variety of beverages are analyzed including almond milk, black tea, strawberry banana juice, amber lager, and pumpkin ale. The GERSTEL MPS is used in combination with a CIS 4 inlet and thermal desorber for automated thermal desorption of the TF-SPME devices.
