Polymer characterization.

The Triple Detector Array (TDA) is said to set the standard for GPC/SEC technology and is the preferred method for characterizing natural and synthetic polymers and proteins. The TDA employs a concentration detector, viscometer and light scattering detector acting in concert, with each detector providing complementary but different information. The TDA is said to combine the power of traditional triple detection with all new UV-VIS and low angle light scattering (LALS) options. Concentration can be measured with an RI, UV or both. When used simultaneously, the RI and UV are said to provide information necessary for the determination of copolymer composition. LALS is said to be the only GPC detection method that provides absolute molecular weights without extrapolation or correction. (Viscotek)
