Dionex (Sunnyvale, California) has agreed to purchase Caliper Life Sciences’ (Hopkinton, Massachusetts) AutoTrace solid-phase extraction (SPE) products, including the AutoTrace SPE workstation, which is designed to automate the extraction of large-volume aqueous samples before analysis. The system can be used for applications such as the EPA Methods 500 and 600 series for environmental testing of drinking water. Dionex intends to use the addition of the product line to focus on sample preparation in the water industry and to provide ion chromatography and high performance liquid chromatography methods for environmental analysis.
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.
