Chemists from the University of North Dakota (Grand Forks, North Dakota) used solid-phase microextraction (SPME) to extract aldehydes from an aqueous solution. They evaluated several SPME techniques, including headspace extraction, liquid-phase extraction, and on-fiber derivatization. The liquid-phase SPME method was the optimal method, achieving limits of detection in the 0.1–4.4 µg/L for most of the analytes. Headspace SPME with an on-fiber derivatization was less sensitive and was unable to detect several compounds.
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).
