This 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.

A new method has been created for determining N-nitrosamines (NAs) in pharmaceutical preparations using liquid chromatography with tandem mass spectrometry.

A new approach to characterizing human milk oligosaccharides was developed using a combination of liquid chromatography, mass spectrometry, and other techniques.

New types of smart proteolytic samplers were tested for their effectiveness in liquid chromatography-mass spectrometry (LC–MS)-based protein quantification.
