Triple Detector Array Utilizes LALS and UV-Vis
Booth 5932. The triple detector array (TDA) for GPC/SEC technology characterizes natural and synthetic polymers and proteins. It uses a concentration detector, viscometer and light scattering detector acting in concert. Each detector provides complementary but different information. The TDA combines the power of traditional triple detection with UV-Vis and low angle light scattering (LALS) options. Measuring concentration with an RI, UV or both is possible. When used simultaneously, the RI and UV provide information necessary for determining copolymer composition. LALS provides absolute molecular weights without extrapolation or correction. Operating at an angle of 7°, LALS directly measures molecular weight for a range of natural and synthetic polymers and proteins.
