Triple Detection and GPC Viscosity

    Triple detection (light scattering, viscosity and refractive index) is available for near ambient GPC with tetrahydrofuran and chloroform, and for aqueous based eluents. Other solvents suitable for use at near ambient conditions can also be considered. GPC-viscosity is available for the high temperature GPC analysis of polyolefins.

    Light scattering and or viscosity detection are often used to provide the true molecular weight data of plastic and other polymer samples as opposed to expressing them as “equivalent” molecular weights or applying a possible questionable mathematical correction. These approaches are valuable in providing information on the differences in structure or composition between samples.
