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.
HPLC 2025 Preview: Functionalized Monoliths as Selective Sample Preparation Materials
May 16th 2025Analyzing trace compounds from complex samples often requires purification and pre-concentration, and online coupling of solid-phase extraction (SPE) with liquid chromatography (LC) helps minimize analysis time and solvent/sample use. Monoliths with large macropores are ideal for this coupling due to their low back pressure and versatility in various formats.
