The RImax is a modular system consisting of the GPCmax integrated solvent and sample delivery module, refractive index detector, column oven, plus the same powerful OmniSEC software used in the TDAmax research system. Relative molecular weight measurement and molecular weight distribution of polymers and proteins Autosampler incorporated to increase throughput and improve repeatability In line degasser and automatic eluent sensor for out of solvent warning Column oven to give repeatable elution profiles Advanced GPC/SEC software capable of going from data to results in just two clicks Upgradable to add light scattering (RALS and LALS) intrinsic viscosity and UV detectors, to provide absolute molecular weight, molecular size, structure and composition of proteins and polymers 21 CFR part 11 compliant
