In-Syringe Liquid-Liquid Microextraction of Drug
Researchers from Soochow University (Taipei, Taiwan, Republic of China) applied an in-syringe liquid-liquid microextraction technique to prepare a clenbuterol sample for analysis by high performance liquid chromatography (HPLC).
Researchers from Soochow University (Taipei, Taiwan, Republic of China) applied an in-syringe liquid-liquid microextraction technique to prepare a clenbuterol sample for analysis by high performance liquid chromatography (HPLC). The researchers first drew a 10-L volume of formic acid into a 100-L syringe and then a 20-L volume of a sedimented sample containing the drug. Repeated cycling of the plunger in and out enabled extraction of the drug into the aqueous formic acid phase. They then used reversed-phase HPLC with a C18 column and an aqueous acetonitrile mobile phase to analyze the extract.

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).
