This is what we consider to be the standard Gel Permeation Chromatography GPC/SEC research package. Absolute values for molar mass and intrinsic viscosity without calibration at all. Plus, dn/dc and mass balance.
With this system you can determine Mark-Howink coefficient for your sample with a single injection or perform branching calculations without assumptions. This package consists of WGE pump, autosampler, refractometer/viscometer dual-detector, BI-MwA 7-angles SLS and ParSEC-Enhanced SEC software.
