SPME with Carbon Nanotubes for Analysis of Phenols
Scientists from Xiamen University (Xiamen, China) employed solid-phase microextraction (SPME) with a carbon nanotube?coated fiber to analyze phenols in aqueous samples.
Scientists from Xiamen University (Xiamen, China) employed solid-phase microextraction (SPME) with a carbon nanotube–coated fiber to analyze phenols in aqueous samples. The final analysis was performed using high performance liquid chromatography (HPLC) with UV absorbance detection. The fiber coating reportedly did not swell in organic solvents nor separate from the substrate, and it had high mechanical strength. They were able to perform more than 80 analyses using one fiber. Detection limits were 0.9–3.8 ng/mL, and recoveries from spiked seawater and tap water were 87.5–102%.
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).
