The Agilent 1260 Infinity Multi-Detector GPC/SEC System is a powerful tool for polymer characterization. The signals from a concentration sensitive detector such as refractive index (RI) or ultra-violet (UV) coupled with light scattering and viscometry can be used to determine the absolute molecular weight, size, andshape of the polymer in solution. This Application Note shows the value of the echnique applied to the analysis of three very structurally different materials and illustrates the advantages of using multi一detection GPC/SEC to study a range of polymers.
