Molecularly Imprinted Polymer SPE of Quinolones
Researchers from Hebei University and Baoding University (both in Baoding, China) used water-compatible molecularly imprinted polymers as a sorbent for solid-phase extraction (SPE) of nine quinolones from urine samples.
Researchers from Hebei University and Baoding University (both in Baoding, China) used water-compatible molecularly imprinted polymers as a sorbent for solid-phase extraction (SPE) of nine quinolones from urine samples. They used UV and IR spectroscopy and proton nuclear magnetic resonance spectroscopy to investigate the sorbent’s molecular recognition mechanisms. The sorbent was able to extract the analytes selectively and simultaneously eliminate matrix interferences. Detection limits for the method reportedly were in the 0.036–0.10 µg/mL range.
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).
