Ultra-High Resolution Chromatography Using 500 mm UHPLC Columns for Detection Of Hidden Sample Components
The Column
LC method development for new drug candidates or screening methods for new active structures in botanicals present the same type of challenges: How do I know that I have separated all main components, as well as important, sometimes hidden, impurities? Is my resolution good enough? Am I missing small, co-eluting peaks?

Thermodynamic Insights into Organic Solvent Extraction for Chemical Analysis of Medical Devices
April 16th 2025A new study, published by a researcher from Chemical Characterization Solutions in Minnesota, explored a new approach for sample preparation for the chemical characterization of medical devices.
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.
