Ionic Liquid-Based Single-Drop Microextraction of Chlorobenzenes
A research group from the University of Valencia (Valencia, Spain) and the University of Alicante (Alicante, Spain) used ionic liquid?based single-drop microextraction followed by gas chromatography (GC) to analyze chlorobenzenes in real water samples.
A research group from the University of Valencia (Valencia, Spain) and the University of Alicante (Alicante, Spain) used ionic liquid–based single-drop microextraction followed by gas chromatography (GC) to analyze chlorobenzenes in real water samples. The method involves thermal desorption of the analytes from the ionic liquid droplet to the GC system using a commercially available thermodesorption system. They determined 10 chlorobenzenes in water samples, with RSDs of 2–17% and limits of detection of 1–4 ng/L.
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.
