Ultrasound-Assisted Extraction of Haloacetic Acids from Vegetables
Chemists from the University of Cordoba (Cordoba, Spain) used a continuous ultrasound-assisted approach to extract nine haloacetic acids from vegetables and conversion to methyl esters for gas chromatography (GC) analysis.
Chemists from the University of Cordoba (Cordoba, Spain) used a continuous ultrasound-assisted approach to extract nine haloacetic acids from vegetables and conversion to methyl esters for gas chromatography (GC) analysis. Acidic methanol was used as the extraction solvent, and simultaneous extraction and derivatization was complete in 15 min. The esterified haloacetic acids were isolated after sample preparation by liquid?liquid extraction with n-hexane and subsequent GC analysis with electron-capture detection.

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).
