| functional principle | Gel permeation chromatography (GPC), also known as size exclusion chromatography (SEC), is a technique used to separate mixtures based on their size. Separated molecules are detected by a concentration detector (conventional detection), e.g. a refractive index detector (RI), whereby the result of the size distribution refers to the calibration with the polymer standards used. Oder es werden zur Detektion mehrere Detektoren verwendet (universelle Detektion oder Triple-Detektion mit Lichtstreuung, Viskosimeter und RI-Detektor), die die Berechnung der Verteilung des absoluten Molekulargewichts, der Molekülgröße und der intrinsischen Viskosität sowie von Informationen zur makromolekularen Struktur, Konformation, Aggregation und Verzweigung erlauben. |
| Typical applications | Characterization of natural and synthetic polymers, biopolymers, proteins and nanoparticles |
| Norms and standards | Various chapters and monographs from EP and USP and other standards |
