Researchers from the New Jersey Institute of Technology (Newark, New Jersey) prepared a micro solid-phase extraction (SPE) device consisting of carbon nanotubes packed in the needle of a syringe. They used the device for sampling, analyte enrichment, and sample introduction and used both single- and multiwalled carbon nanotubes as sorbents. The needle held approximately 300 µg of the carbon nanotube sorbent. They found the packed carbon nanotube beds to provide extraction efficiencies as high as 27% and enrichment factors of close to 7. They reported that the method was linear, reproducible, and achieved low method detection limits of 0.1–3 ng/mL for MWNTs.

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).
