Expanding the GPC/SEC experiment beyond conventional limits using viscometry and light scattering detection
2 Jul 2023In this application note, Agilent presents the Agilent 1260 Infinity Multi-Detector GPC/SEC System, a powerful tool for polymer characterization. The system utilizes signals from a concentration sensitive detector, such as refractive index (RI) or ultra-violet (UV), along with light scattering and viscometry. These signals enable the determination of the absolute molecular weight, size, and shape of the polymer in solution. The application note demonstrates the value of this technique by analyzing three structurally different materials. It highlights the advantages of using multi-detection GPC/SEC to study a range of polymers.
