Advanced triple detector for GPC/SEC

Apr 16 2024

Testa Analytical unveils Trinity, an innovative triple detector designed specifically for Gel Permeation Chromatography/Size Exclusion Chromatography (GPC/SEC). This advanced system represents a significant leap forward in the accurate characterisation of macromolecules, including proteins, polysaccharides, and synthetic polymers.

Triple Detection GPC/SEC has long been regarded as the gold standard technique for comprehensive molecular analysis. Combining light scattering and viscometer detectors with a refractive index (RI) detector, this technique provides invaluable insights into molecular weight and structure.

Drawing upon decades of GPC/SEC innovation, Testa Analytical has developed Trinity, a system capable of unravelling the complexities of synthetic polymers and natural macromolecules. Trinity integrates high-performance chromatographic detector technologies with user-friendly software, offering unparalleled insights into molecular structure.

Trinity's Differential Refractive Index (DRI), Multi-Angle Light Scattering (MALS), and Viscometer detectors provide a powerful combination for investigating a compound's physical structure. This triple detector system delivers absolute values for molecular weights, intrinsic viscosity, and precise Mark-Howink coefficient data, enabling researchers to gain deeper insights into chain flexibility and molecular density.

Each detector within Trinity features independent temperature control, ensuring precise and reproducible results day after day. Supported by a robust software suite, Trinity offers intuitive operation and comprehensive data analysis tools, empowering researchers to generate and present results with ease.
