SPE of Pesticides from Fruit Juices with Carbon Nanotubes
A research group from the University of La Laguna and ICIA (both in La Laguna, Tenerife, Canary Islands, Spain) used multiwalled carbon nanotubes as a solid-phase extraction (SPE) medium for extracting eight organophosphorus pesticides from various commercial apple, grape, orange, and pineapple juices.
A research group from the University of La Laguna and ICIA (both in La Laguna, Tenerife, Canary Islands, Spain) used multiwalled carbon nanotubes as a solid-phase extraction (SPE) medium for extracting eight organophosphorus pesticides from various commercial apple, grape, orange, and pineapple juices. The pesticides were ethoprophos, diazinon, chlorpyriphos-methyl, fenitrothion, malathion, chlorpyriphos, fenamiphos, and buprofezin. In this method, the SPE step was followed by gas chromatography with nitrogen–phosphorus detection.
Analytical Challenges in Measuring Migration from Food Contact Materials
November 2nd 2015Food contact materials contain low molecular weight additives and processing aids which can migrate into foods leading to trace levels of contamination. Food safety is ensured through regulations, comprising compositional controls and migration limits, which present a significant analytical challenge to the food industry to ensure compliance and demonstrate due diligence. Of the various analytical approaches, LC-MS/MS has proved to be an essential tool in monitoring migration of target compounds into foods, and more sophisticated approaches such as LC-high resolution MS (Orbitrap) are being increasingly used for untargeted analysis to monitor non-intentionally added substances. This podcast will provide an overview to this area, illustrated with various applications showing current approaches being employed.
