Viscosimetric detection in size‐exclusion chromatography (SEC/GPC): The Goldwasser method and beyond

Size‐exclusion chromatography (SEC or GPC) is the most widely used separation method to characterize polymers. The high level of complexity of most polymeric materials necessitates the use of not only concentration‐sensitive detection but also structure‐sensitive detection. Viscometry is usually used in conjunction with a concentration‐sensitive detector and universal calibration to determine molecular weights of polymers. Goldwasser proposed to...
