 GPC-MALS Analysis for Precise Polymer Characterization

At Moore Analytical, we offer Gel Permeation Chromatography with Multi-Angle Light Scattering (GPC-MALS) to deliver absolute molecular weight determination and detailed structural insights for polymers, plastics, and complex macromolecules.

Our system features the Wyatt Technology MALS detector coupled with the Wyatt Optilab refractive index (RI) detector, providing high-resolution molecular weight distributions without relying on traditional column calibration standards.

Why Choose GPC-MALS?

  • Absolute Molecular Weights: Eliminate dependence on conventional calibration curves. Get true molecular weight values across a broad range (500 Da to 10^7 Da).

  • Molecular Size (Rg) Determination: Measure radius of gyration for branched polymers, copolymers, and nanoparticles.

  • Insight into Polymer Architecture: Detect aggregation, branching, and structural variations that standard GPC cannot resolve.

  • Comprehensive Polymer Profiling: Ideal for quality control, material development, or failure analysis in the plastics and polymer sectors.

Typical Applications:

  • Polymer molecular weight and distribution analysis

  • Copolymer composition and architecture studies

  • Nanoparticle and micelle characterization

  • Biopolymer (e.g., polysaccharides, proteins) aggregation analysis

Let Moore Analytical support your R&D and manufacturing processes with accurate, reproducible polymer data to help you make informed decisions.
