Liquid-Liquid-Liquid Microextraction of Nerve Agents
Researchers from Vertox Laboratory, Defence Research and Development Establishment (Gwalior, India) used a liquid-liquid-liquid microextraction technique followed by liquid chromatography?mass spectrometry (LC?MS) to examine alkyl alkylphosphonic acids, which are important environmental markers of nerve agents.
Researchers from Vertox Laboratory, Defence Research and Development Establishment (Gwalior, India) used a liquid-liquid-liquid microextraction technique followed by liquid chromatography–mass spectrometry (LC–MS) to examine alkyl alkylphosphonic acids, which are important environmental markers of nerve agents. In their technique, the acids were extracted froman acidified aqueous phase to an organic phase located in the pores of a hollow fiber. They were then back extracted into an alkaline acceptor phase in the lumen of the fiber. The researchers validated the method and then applied it to detection of the acids in a water sample provided by the Organization for Prohibition of Chemical Weapons during a proficiency test.
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).
