Triple detector array.

The TDA triple detector array is said to set the standard for GPC/SEC technology and is said to be 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 complimentary 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. Concentrations 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 light scattering technology is said to be the only GPC detection method that provides absolute molecular weights with extrapolation or correction. Operating at an angle of 7[degrees], LALS directly measures molecular weight for an extensive range of natural and synthetic polymers and proteins. (Viscotek)
