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.
Modern HPLC Strategies That Improve Retention and Peak Shape for Basic Analytes
August 16th 2024In high-performance liquid chromatography (HPLC), it is common for bases and unreacted ionized silanols on silica-based columns to cause irreproducible retention, broad peaks, and peak tailing when working with basic analytes. David S. Bell, Lead Consultant at ASKkPrime LLC offers innovative HPLC strategies that can help mitigate such issues.
Advancing Chromatographic Analysis: A Novel Composite Technology for SPE
July 22nd 2024Solid Phase Extraction (SPE) is vital for chromatographic analysis. However, traditional loose-packed SPE products struggle with channelling and inconsistent resin mass, resulting in poor recovery and reproducibility. Discover how innovative composite technology overcomes these challenges to transform sample preparation, ensuring reliable and sensitive chromatographic data.
