# Analytical Limits of LC-MS Mass Confirmation and Peptide Sequencing Liquid chromatography-mass spectrometry (LC-MS) and tandem mass spectrometry (LC-MS/MS) represent cornerstone analytical techniques for evaluating the molecular weight, purity, and primary structure of synthetic peptides and recombinant proteins [1]. While intact mass measurement provides initial confirmation of molecular formula adherence, establishing definitive sequence integrity requires […]
