Influence of Concentration in Conventional GPC/SEC and Advanced Detection GPC/SEC
March 21st 2025Sample concentration is a parameter that can influence the quality of gel permeation chromatography/size-exclusion chromatography (GPC/SEC) separations and the obtained results. Understanding this influence can help to support the development of reliable GPC/SEC methods.
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.
