Using Uncertainty Analysis to Optimize GPC System Performance (from Boston ACS meeting, 2010)

Introduction GPC when coupled with Static Light Scattering (SLS) is a fairly modern and powerful technique for determining absolute molecular weight values without the need to rely on traditional column calibration. In GPC-SLS the signal intensity levels rather than elution times are evaluated quantitatively. In addition, unlike in polymer standard calibration, details of the accurate […]
