Liquid-Liquid Extraction of Polar Organic Compounds
A research group from Soochow University (Taipei, Taiwan) have used a dispersive liquid?liquid microextraction technique in conjunction with an in-syringe back-extraction method to extract a polar organic compound from an aqueous sample before liquid chromatography (LC) analysis.
A research group from Soochow University (Taipei, Taiwan) have used a dispersive liquid?liquid microextraction technique in conjunction with an in-syringe back-extraction method to extract a polar organic compound from an aqueous sample before liquid chromatography (LC) analysis. Clenbuterol was extracted from an aqueous sample using a water-immiscible organic solvent, and the analyte was recovered in the organic solvent by a centrifugation step. The analyte was then back-extracted in a syringe from the organic solvent into an aqueous solution in preparation for injection into an LC system.

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).
