A research group from the Mendel University of Agriculture and Forestry (Brno, Czech Republic) and the Academy of Sciences of the Czech Republic (Trebon, Czech Republic) combined solid-phase exraction (SPE) and supercritical fluid extraction (SFE) using an SPE cartridge incorporated in an SFE cell to extract benzoic acid and cinnamic acid derivatives from microalgae and cyanobacteria samples.
A research group from the Mendel University of Agriculture and Forestry (Brno, Czech Republic) and the Academy of Sciences of the Czech Republic (Trebon, Czech Republic) combined solid-phase exraction (SPE) and supercritical fluid extraction (SFE) using an SPE cartridge incorporated in an SFE cell to extract benzoic acid and cinnamic acid derivatives from microalgae and cyanobacteria samples. The compounds were further analyzed and identified by high performance liquid chromatography (HPLC) with electrospray mass spectrometry. The researchers found that the technique could be useful for analyzing various plant species for trace amounts of phenol 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.
