Gel permeation chromatography (GPC) is a type of molecular sieving chromatography, where a sample is separated into its constituent parts based on their molecular sizes. This is accomplished by ...

The mobile phase is the starting point for this process. What is the sample polymer soluble in? An insoluble polymer cannot be measured by GPC, making the choice of solvent important. For a fast GPC ...

Size exclusion chromatography (SEC) separates components of a sample on the basis of their molecular size. Differential exclusion or inclusion of the molecules is achieved via filtration through a gel ...

Single-detector systems, also known as conventional gel-permeation chromatography (GPC), feature a refractive index (RI) detector, and are used for making molecular weight measurements by comparing ...
