A detailed explanation of SEC (GPC) used for evaluating the molecular weight of polymers! (For SEC of proteins, please refer to the "Bioseparation Handbook.")
This document is a technical material that explains size exclusion chromatography (SEC). We will introduce the basic principles of SEC, measurement methods, and examples of measurements of actual samples. [Contents (excerpt)] - Physical properties and molecular weight of polymers, molecular weight distribution - Measurement methods for average molecular weight and molecular weight distribution - Molecular weight measurement using SEC - Column selection methods - Elution solvents - Sample concentration and injection volume - SEC measurement of super high molecular weight - High-temperature SEC *For more details, please refer to the PDF document or feel free to contact us.
