Characterizing Polymer Architecture: Importance, Challenges, Solution
Polymers are gaining more attention in many new fields such as pharmaceutical applications. However, optimizing the final properties of the polymers associated with these new application areas is challenging for chemists and analysts. Polymer architecture plays a crucial role to optimize the end use or process-related properties. Size exclusion chromatography in combination with advanced detectors such as light scattering, viscometer, and refractive index is a powerful tool for the comprehensive characterization of macromolecules with various architectures. In this podcast, Dr. Subin Damodaran will explain how to understand the structural properties of a polymer by providing their molecular sizes such as radius of gyration (Rg ) and hydrodynamic radius (Rh), and intrinsic viscosity.
The Next Frontier for Mass Spec: Maximizing Ion Utilization
January 20th 2025MOBILion has introduced a new high-resolution mass spectrometry (HRMS) approach that can increase speed and sensitivity in omics applications. The parallel accumulation with mobility aligned fragmentation (PAMAF) approach substantially increases the fraction of ions used for MS analysis by replacing the functionality of the quadrupole with high-resolution ion mobility.
