SPME-GC-MS Analysis of Cigarette Smoke
A researcher from Shagrao Normal University (Shangrao, Jiangxi Province, China) used solid-phase microextraction (SPME) followed by gas chromatography?mass spectrometry (GC?MS) to analyze volatile organic compounds (VOCs) in cigarette smoke.
A researcher from Shagrao Normal University (Shangrao, Jiangxi Province, China) used solid-phase microextraction (SPME) followed by gas chromatography–mass spectrometry (GC–MS) to analyze volatile organic compounds (VOCs) in cigarette smoke. The researcher used a home-made smoking machine to produce the smoke. Various SPME fibers and desorption conditions were studied. The study found that the best fiber was coated with divinylbenzene–carboxen–polydimethylsiloxane and that a desorption temperature–time of 250 °C for 3 min was optimal. The method identified 70 VOCs and provided a precision of 2–11%.
RAFA 2024 Highlights: Contemporary Food Contamination Analysis Using Chromatography
November 18th 2024A series of lectures focusing on emerging analytical techniques used to analyse food contamination took place on Wednesday 6 November 2024 at RAFA 2024 in Prague, Czech Republic. The session included new approaches for analysing per- and polyfluoroalkyl substances (PFAS), polychlorinated alkanes (PCAS), Mineral Oil Hydrocarbons (MOH), and short- and medium-chain chlorinated paraffins (SCCPs and MCCPs).
