Dispersive Liquid-Phase Microextraction of Aromatic Amines in Water
Scientists from Henan Normal University (Xinxiang, China) and the University of Science and Technology Beijing (Beijing, China) developed an ultrasound-assisted ionic liquid dispersive liquid-phase microextraction procedure for determining four aromatic amines in water samples.
Scientists from Henan Normal University (Xinxiang, China) and the University of Science and Technology Beijing (Beijing, China) developed an ultrasound-assisted ionic liquid dispersive liquid-phase microextraction procedure for determining four aromatic amines in water samples. The aromatic amines — 2,4-dichloroaniline, 1-naphthylamine, 6-chloroaniline, and N,N-dimethylaniline — were analyzed after the extraction procedure by high performance liquid chromatography with UV detection. The method was used successfully to analyze real water samples, and they obtained spiked recoveries of 92.2–119.3%.
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).
