The Viscotek 270 detector is the ideal building block for a modular advanced GPC/SEC system. It can be specified as a dual detector (viscometer plus light scattering) or as a single detector, either viscometer or light scattering. The Viscotek 270 Detector is available as part of the 270max system, or as a separate module for connection to other chromatography components, such as the Viscotek GPCmax or other types of GPC/SEC system. In its full Dual Detector format the 270 contains a differential viscometer detector and low angle light scattering detector. When used in conjunction with an RI detector, the triple detection system provides advanced chromatography where each detector gives complementary information on the molecule being analyzed. Results include concentration, molecular weight distribution, intrinsic viscosity, molecular size (Rh and Rg) and branching information. The addition of a photodiode array UV detector provides additional compositional data. Sensitive absolute molecular weight determination of small polymers, using Right angle light scattering (RALS). Absolute molecular weight of polymers without extrapolation using low angle light scattering (LALS). Polymer structure (including branching) information using intrinsic viscosity detector. Molecular size in terms of hydrodynamic radius (Rh) and Rg. 21 CFR part 11 compliant. Full suite of calibration and GPC/SEC calculation types.
