Researchers from US EPA National Exposure Research Laboratory (Research Triangle Park, North Carolina) and East Carolina University (Greenville, North Carolina) used supercritical fluid extraction (SFE) to recover aflatoxin B1 from fortified soil.
Researchers from US EPA National Exposure Research Laboratory (Research Triangle Park, North Carolina) and East Carolina University (Greenville, North Carolina) used supercritical fluid extraction (SFE) to recover aflatoxin B1 from fortified soil. They examined the effects of temperature, pressure, modifier and modifier percentage, and extraction type on the analysis. They found that desorption from the soil was the limiting factor in analyte recovery and that the static phase was more important than the dynamic phase.
Study Explores Thin-Film Extraction of Biogenic Amines via HPLC-MS/MS
March 27th 2025Scientists from Tabriz University and the University of Tabriz explored cellulose acetate-UiO-66-COOH as an affordable coating sorbent for thin film extraction of biogenic amines from cheese and alcohol-free beverages using HPLC-MS/MS.
Multi-Step Preparative LC–MS Workflow for Peptide Purification
March 21st 2025This article introduces a multi-step preparative purification workflow for synthetic peptides using liquid chromatography–mass spectrometry (LC–MS). The process involves optimizing separation conditions, scaling-up, fractionating, and confirming purity and recovery, using a single LC–MS system. High purity and recovery rates for synthetic peptides such as parathormone (PTH) are achieved. The method allows efficient purification and accurate confirmation of peptide synthesis and is suitable for handling complex preparative purification tasks.
