Dispersive Liquid-Liquid Microextraction GC Method
Researchers from National Tsing Hua University (Hsinchu, Taiwan) developed a dispersive liquid?liquid microextraction (DLLME) method based on solidification of a floating organic drop and combined it with gas chromatography with either electron-capture or mass spectrometry detection.
Researchers from National Tsing Hua University (Hsinchu, Taiwan) developed a dispersive liquid–liquid microextraction (DLLME) method based on solidification of a floating organic drop and combined it with gas chromatography with either electron-capture or mass spectrometry detection. The method reportedly is simple, inexpensive, and precise. It also avoids the use of high-toxicity solvents usually used in DLLME. They used halogenated organic compounds in water as the model compounds for the method.
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).
