SPME-Headspace GC Analysis of BTEX in Waste Treatment Effluent
Researchers from Sao Cristovao and Salvador, Brazil employed a solid-phase microextraction (SPME-headspace gas chromatography (GC) method to analyze benzene, toluene, ethylbenzene, and xylenes (BTEX) in water released from a waste treatment plant.
Researchers from Sao Cristovao and Salvador, Brazil employed a solid-phase microextraction (SPME-headspace gas chromatography (GC) method to analyze benzene, toluene, ethylbenzene, and xylenes (BTEX) in water released from a waste treatment plant. They optimized the extraction step using fractional factorial and central composite designs with experimental factors such as saline concentration, extraction time, desorption time, agitation velocity, and headspace volume. The procedure was based on direct SPME at 50 C using a polydimethylsiloxane fiber.

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).
