Supercritical Fluid Extraction of Lipids
Researchers at the Virginia Tech (Blacksburg, Virginia) Department of Chemistry have used supercritical fluid extraction with methanol-modified carbon dioxide to separate polar lipid fractions from crude soybean lecithin.
Researchers at the Virginia Tech (Blacksburg, Virginia) Department of Chemistry have used supercritical fluid extraction with methanol-modified carbon dioxide to separate polar lipid fractions from crude soybean lecithin. Pure carbon dioxide was used to remove the neutral lipids. The phosphatidyl choline-enriched fraction of the soybean lecithin was the target of this extraction. They isolated and identified six components in the crude soybean lecithin extract.
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.
