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 ...

Testa Analytical Solutions has published the first in a new series of online training presentations for scientists involved with, or interested in learning more about, Gel Permeation Chromatography ...

Size-exclusion chromatography (SEC) or gel permeation chromatography (GPC) is an extensively used method for characterizing a wide range of macromolecules, which includes but is not limited to bulk or ...

Gel Permeation Chromatography (GPC) is a chromatographic technique that separates molecules based on their relative size in solution. This allows us to determine the molecular weight distribution of ...

Molecular weight is a main feature employed when characterizing polymer-based products. The term describes the molar mass distribution of polymer chains which can significantly vary within polymers of ...

TESTA Analytical announces its high-performance viscometer is now available to chromatography manufacturers interested in expanding their GPC/SEC capabilities and serving the most demanding clients ...

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 ...
