Hot Water Extraction of Antibacterials from Eggs
Researchers from Universita ?La Sapienza? (Rome, Italy) used a matrix solid-phase dispersion technique with hot water as the extracting solvent to extract seven quinolone antibacterial agents from egg samples.
Researchers from Universita “La Sapienza” (Rome, Italy) used a matrix solid-phase dispersion technique with hot water as the extracting solvent to extract seven quinolone antibacterial agents from egg samples. They used liquid chromatography with tandem mass spectrometry to analyze the extracted analytes. The researchers deposited the egg sample containing the analytes on crystobalite sand and packed it into an extraction cell. Acidified water was pumped through the cell, which was maintained at 100 °C. They validated the method in terms of ruggedness, specificity, linearity, within-laboratory reproducibility, and detection capability, and afterward conducted a depletion study of enrofloxacin and ciprofloxacin in eggs.
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).
