The Viscotek advanced GPC/SEC detectors can be used to upgrade any existing system to triple detection to add the power of light scattering (low angle or right angle) or multi-angle light scattering (SEC-MALS) to measure absolute molecular weight, or a viscometer to measure intrinsic viscosity. Concentration detectors such as refractive index and UV are also available.
