High-precision GPC/SEC triple detector

07 Oct, 2025

Testa Analytical has introduced Trinity, a state-of-the-art triple detector platform designed to push Gel Permeation Chromatography (GPC) and Size Exclusion Chromatography (SEC) to new heights. This system delivers comprehensive, accurate insights into macromolecules - from proteins and polysaccharides to synthetic polymers.

Unlike standard GPC/SEC setups, Trinity doesn’t just measure molecular weight. Its integrated Differential Refractive Index (DRI), Multi-Angle Light Scattering (MALS), and Viscometer detectors provide absolute molecular weight, intrinsic viscosity, and Mark-Houwink coefficients. This combination allows researchers to probe chain flexibility, molecular density, and branching with confidence, revealing structural details that go far beyond conventional analysis.

Precision and reproducibility are at the heart of Trinity. Each detector features independent temperature control, ensuring consistent performance day after day. Paired with intuitive, feature-rich software, Trinity makes it easy to capture, analyse, and visualise complex data without compromising on detail.

For labs seeking a deeper understanding of macromolecular architecture, Trinity offers a robust, reliable, and user-friendly solution for high-level GPC/SEC analysis.
