Dynamic Liquid-Phase Extraction of Anti-Inflammatory Drugs in Urine
Researchers at the University of Cordoba (Cordoba, Spain) used dynamic liquid-phase microextraction with an ionic liquid as the acceptor phase to extract six nonsteroidal anti-inflammatory drugs from human urine samples.
Researchers at the University of Cordoba (Cordoba, Spain) used dynamic liquid-phase microextraction with an ionic liquid as the acceptor phase to extract six nonsteroidal anti-inflammatory drugs from human urine samples. The extractant liquid was 1-butyl-3-methylimidazolium hexafluorophosphate. The researchers achieved limits of detection ranging from 38 ng/mL to 70 ng/mL and repeatabilities ranging from 2.1% to 3.8%. The analytical method was optimized with respect to chemical, physical, and hydrodynamic variables. The method was found to be useful for drugs in urine in the concentration range 0.1?10 g/mL.
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).
