Mixed-Mode SPE Used in Analysis of Pharmaceuticals in Wastewater
Researchers from Stockholm University (Stockholm, Sweden) and Nankai University (Tianjin, China) used a serial mixed-mode cation-exchange and anion-exchange solid-phase extraction (SPE) method to extract 15 basic, neutral, and acidic pharmaceutical compounds from wastewater.
Researchers from Stockholm University (Stockholm, Sweden) and Nankai University (Tianjin, China) used a serial mixed-mode cation-exchange and anion-exchange solid-phase extraction (SPE) method to extract 15 basic, neutral, and acidic pharmaceutical compounds from wastewater. Separate mixed-mode cation- and anion-exchange columns were used in series. They used high performance liquid chromatography with quadropole time-of-flight mass spectrometry to analyze the extracted compounds. The recovery for the SPE method in the analysis of sewage treatment plant wastewater averaged 80%.
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).
