High-performance triple detector system for GPC/SEC

Testa Analytical has introduced Trinity, a high-performance triple detector system for Gel Permeation Chromatography / Size Exclusion Chromatography (GPC/SEC), building on decades of expertise in macromolecular characterisation.

Designed for complete and accurate analysis of proteins, polysaccharides, and synthetic polymers, Trinity integrates advanced chromatographic detector technologies with powerful yet intuitive software in a single platform.

The system combines Differential Refractive Index (DRI), Multi-Angle Light Scattering (MALS), and a Viscometer to deliver absolute values for molecular weights, intrinsic viscosity, and precise Mark-Houwink coefficients. This enables researchers to probe chain flexibility, molecular density, and branching with confidence - providing reliable, data-driven insight into macromolecular structure beyond molecular weight alone.

Each detector within Trinity features independent temperature control, ensuring consistent precision and reproducibility day after day. The supporting software suite offers intuitive operation and comprehensive tools for processing and presenting results, making advanced GPC/SEC analysis both accessible and robust.
