Gel permeation chromatography (GPC) and size exclusion chromatography (SEC) describe the separation of molecules based only on their molecular size. Using an AZURA® GPC it is possible to run GPC/SEC applications with aqueous as well as organic solvents, when changing the system modules with the suitable compatibility.
