Analysis of Phenolic Compounds in Water
Chemists from Normal University and Wuhan University (both Wuhan, China) used an improved liquid-liquid-liquid microextraction method in the analysis of four phenolic compounds in water.
Chemists from Normal University and Wuhan University (both Wuhan, China) used an improved liquid-liquid-liquid microextraction method in the analysis of four phenolic compounds in water. They used a vial insert as the acceptor phase container. The small diameter of the bottom of the vial insert caused a larger contact area between the acceptor phase and the vial insert and reportedly enabled increased the stability of the microdrop. Because more acceptor phase could be held in the improved method, the sensitivity was also increased. The researchers chose aqueous ammonia as the acceptor phase and toluene as the organic phase.
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).
