Learn how SEC integration theory converts chromatographic detector response into molecular-weight information, including SEC baselines, noise treatment, internal-standard flow correction, detector-response types, molecular-weight averages and molecular-weight fractions.

A detailed guide to SEC calibration theory, covering molecular-weight averages, narrow and broad standards, universal calibration, hydrodynamic volume, intrinsic viscosity, Mark–Houwink relationships, and the Integral, Hamilec, and Yau methods used in size exclusion chromatography.

Chromperfect GPC software provides specialized SEC analysis, molecular weight distribution calculations, calibration options, and reporting for polymer laboratories using Chromperfect or supported third-party data.
