Cold Fiber SPME Device
Researchers from the University of Waterloo (Waterloo, Canada) designed and constructed a cold fiber solid-phase microextraction (SPME) device and applied it to the analysis of off flavors in a rice sample.
Researchers from the University of Waterloo (Waterloo, Canada) designed and constructed a cold fiber solid-phase microextraction (SPME) device and applied it to the analysis of off flavors in a rice sample. The device was based on thermoelectric cooling via a three-stage thermoelectric cooler that cooled a copper rod coated with a poly(dimethylsiloxane) hollow fiber that served as the SPME fiber. They examined three compounds in the rice: hexanal, nonanal, and undecanal, which were identified by retention times in a gas chromatography–flame ionization detection system. The cooled fiber device reportedly resulted in better reproducibility and shorter analysis time compared with a conventional solvent extraction method.

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).
