Gathering information about the chemical and physical properties of target analytes is an essential step to effective solid-phase extraction (SPE) method development.
Gathering information about the chemical and physical properties of target analytes is an essential step to effective solid-phase extraction (SPE) method development. Log P, log D and pKa are key analyte characteristics that can have a significant impact on the rapid success of reversed-phase SPE method development. This article explores the value of these chemical properties and demonstrates their importance in efficient reversed-phase SPE method development and optimization.
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.
