Sol-Gel Coatings for SPME
A group of researchers from Universita degli Studi di Parma (Parma, Italy) developed sol-gel?synthesized coatings for solid-phase microextraction (SPME) fibers for analyzing trace-level polycyclic aromatic hydrocarbons in water.
A group of researchers from Universita degli Studi di Parma (Parma, Italy) developed sol-gel-synthesized coatings for solid-phase microextraction (SPME) fibers for analyzing trace-level polycyclic aromatic hydrocarbons in water. The researchers measured the fibers' film thickness, porosity, thermal stability, and pH resistance. A diethoxydiphenylsilane-based coating was found to provide thermal stability to temperatures as high as 400 C. Limits of detection were better than those obtained using a polydimethylsiloxane fiber.
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).
