Hollow-Fiber Liquid-Phase Microextraction of Aromatic Amines
Researchers from the Chinese Academy of Sciences (Beijing, China) and the University of Science and Technology of China (Hefei, China) used a two- and three-phase hollow-fiber liquid-phase microextraction method to determine aromatic amines in environmental water samples.
Researchers from the Chinese Academy of Sciences (Beijing, China) and the University of Science and Technology of China (Hefei, China) used a two- and three-phase hollow-fiber liquid-phase microextraction method to determine aromatic amines in environmental water samples. The analytes were aniline, 4-nitroaniline, 2,4-dinitroaniline, and dicloran, and they were extracted from basic aqueous samples into the organic membrane phase of the hollow fiber’s wall and then were back extracted into an acidified aqueous acceptor solution in the lumen of the fiber. According to the researchers, the method worked well with real environmental water samples with microgram per liter level analytes.
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).
