Needle Trap Device Used for Headspace Sampling
Workers at the University of Waterloo (Waterloo, Ontario, Canada) combined a needle trap device and a dynamic headspace method to sample an aqueous BTEX (benzene, toluene, ethylbenzene, and p-xylene) mixture.
Workers at the University of Waterloo (Waterloo, Ontario, Canada) combined a needle trap device and a dynamic headspace method to sample an aqueous BTEX (benzene, toluene, ethylbenzene, and p-xylene) mixture. The device consisted of a 22-gauge stainless steel needle filled with divinylbenzene particles. A sequential purge-and-trap approach using a syringe pump followed the sampling step. The researchers obtained 1-ng/mL detection limits for BTEX using the technique.

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).
