Dispersive Liquid-Liquid Microextraction of Antibacterial Agent
Researchers from Universidad de Santiago de Compostela (Santiago de Compostela, Spain) developed a dispersive liquid-liquid microextraction sample preparation method to determine the antibacterial agent triclosan and its environmental transformation product methyl triclosan in water samples.
Researchers from Universidad de Santiago de Compostela (Santiago de Compostela, Spain) developed a dispersive liquid-liquid microextraction sample preparation method to determine the antibacterial agent triclosan and its environmental transformation product methyl triclosan in water samples. The extraction used a ternary mixture of a disperser, an extractant, and a derivatization reagent. Simultaneous derivatization and concentration of both species was achieved. The analysis was performed using gas chromatography with tandem mass spectrometry.
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).
