BTEX in Water Analyzed by Microdrop Extraction and GC-MS
Analysts from the Department of Analytical Chemistry at the University of Cordoba (Cordoba, Spain) used ionic liquid-based, single-drop microextraction followed by gas chromatography with mass spectrometric detection to analyze benzene, toluene, ethylbenzene, and xylene isomers (BTEX) in water.
Analysts from the Department of Analytical Chemistry at the University of Cordoba (Cordoba, Spain) used ionic liquid-based, single-drop microextraction followed by gas chromatography with mass spectrometric detection to analyze benzene, toluene, ethylbenzene, and xylene isomers (BTEX) in water. The ionic extraction liquid, 1-methyl-3-octyl-imidazolium hexafluorophosphate, has a high affinity for the aromatic analytes but is immiscible with water. Repeatability (RSD) for the method reportedly ranged from 3.0% for o-xylene to 5.2% for toluene.
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).
