Sonication-Assisted Extraction of Parabens in Environmental Samples
Scientists from INIA (Madrid, Spain) used ultrasonic-assisted extraction followed by liquid chromatography with triple-quadrupole mass spectrometry detection (LC?MS) to analyze paraben compounds in environmental solid samples.
Scientists from INIA (Madrid, Spain) used ultrasonic-assisted extraction followed by liquid chromatography with triple-quadrupole mass spectrometry detection (LC–MS) to analyze paraben compounds in environmental solid samples. The sonication was performed in small glass columns. The samples were subjected to two consecutive 15-min sonication steps with acetonitrile as the extraction solvent. The sample extracts were evaporated under nitrogen and were subsequently analyzed by LC–MS. The technique was found to be suitable for analyzing methyl, ethyl, isopropyl, propyl, benzyl, and butylparaben in solid samples such as soil and sediments at trace levels.
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).
