Supelco SPE-Precipitation Technology Wins Award
Supelco, a division of Sigma-Aldrich (St. Louis, Missouri), announced that its HybridSPE-Precipitation technology has won the SelectScience.net 2009 Scientists? Choice Award for Best New Separations Product in 2008.
Supelco, a division of Sigma-Aldrich (St. Louis, Missouri), announced that its HybridSPE-Precipitation technology has won the SelectScience.net 2009 Scientists’ Choice Award for Best New Separations Product in 2008. The award was based on an independent poll of more than 25,000 scientists within the SelectScience.net community. The award was announced at Pittcon 2009 in Chicago, Illinois. The product combines protein precipitation with solid-phase extraction (SPE) for the targeted removal of phospholipids and proteins in biological plasma and serum. According to the company, the product includes zirconia-coated particles that exhibit selective affinity toward phospholipids and are nonselective for a range of basic, neutral, and acidic compounds.
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.
