Determination of Headspace Volatiles in Distilled Spirits

A ratio of 4 mL of sample in a 10 mL vial provided an adequate volume for the headspace to evolve, plus enough physical space for the SPME fiber to be exposed. For the fiber, a 50/30 μm divinylbenzene/Carboxen ® /polydimethylsiloxane coating on a 1 cm long StableFlex™ core was used to maximize the variety of compound types extracted.

Detection of Gasoline Residues Present in Household Materials

such as headspace vial heating temperature and time, SPME sampling time, and desorption time, were opti-mized using gasoline-spiked carpet samples prior to data collection. Headspace vials containing household samples were heated at 100 °C for 3 min to transfer vol-atile components from the solid sample matrices to the headspace. Then, SPME
