The current issue (2008.1) of Restek's e-newsletter, "The Restek Buzz," includes an article that summarizes the key advantages of thermal desorption versus solvent extraction in air monitoring applications. Thermal desorption is a gas extraction technique in which sorbent tubes that have been exposed to air samples are heated in a flow of carrier gas. Trapped vapors are desorbed into the carrier gas flow and are transferred into a gas chromatography-mass spectrometry (GC-MS) system. According to the article, thermal desorption offers better sensitivity, desorption efficiency, and reproducibility compared with charcoal-carbon disulfide systems.
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.
