Podcast: The Importance of Multiple Chromatographic Modes for Protein Analysis
Optimizing Chromatographic Conditions for Protein Analysis with theACQUITY UPLC H-Class Bio System
Presented By
Across the pharmaceutical industry, there is growing emphasis on the development of biopharmaceuticals as the next wave of drugs contributing to human health. In this podcast series, we’ll be discussing how chromatographic analyses of biopharmaceuticals, particularly proteins, compare to the more familiar assays of small molecule drugs and the benefits that UPLC® Technology can offer. The types of assays will be described and the basis for choosing them is considered. We’ll also discuss recent developments in ways to improve an analytical method.

An LC–HRMS Method for Separation and Identification of Hemoglobin Variant Subunits
March 6th 2025Researchers from Stanford University’s School of Medicine and Stanford Health Care report the development of a liquid chromatography high-resolution mass spectrometry (LC–HRMS) method for identifying hemoglobin (Hb) variants. The method can effectively separate several pairs of normal and variant Hb subunits with mass shifts of less than 1 Da and accurately identify them in intact-protein and top-down analyses.
The Next Frontier for Mass Spectrometry: Maximizing Ion Utilization
January 20th 2025In this podcast, Daniel DeBord, CTO of MOBILion Systems, describes a new high resolution mass spectrometry approach that promises to increase speed and sensitivity in omics applications. MOBILion recently introduced the PAMAF mode of operation, which stands for parallel accumulation with mobility aligned fragmentation. It substantially increases the fraction of ions used for mass spectrometry analysis by replacing the functionality of the quadrupole with high resolution ion mobility. Listen to learn more about this exciting new development.
