Gel chromatography

Gel chromatography, also known as gel permeation chromatography (GPC) or gel filtration chromatography, is not only used in polymer science, but also in surface technology. In this context, gel chromatography refers to the separation and analysis of substances, especially macromolecules or polymers, which are used in coatings or surface treatments.

In surface technology, polymer materials can be used as components of coatings, paints or thin films. Gel chromatography makes it possible to characterize the molecular mass distribution of these polymers. This is important because the properties of coatings, such as adhesion, hardness, flexibility and resistance, can be directly related to the molecular mass of the polymer components they contain.

By using gel chromatography in surface technology, researchers and engineers can gain insight into the composition of coating materials. This is crucial for the development of high-quality coatings with the desired performance properties. The results of gel chromatography can provide insight into the distribution of molecular mass in coatings, which in turn can influence aspects such as the viscosity, drying time and adhesion of coatings. A precise characterization of the polymer components in coatings is therefore of great importance for the optimization of surface treatments in various industrial applications.

In summary, gel chromatography plays an important role in surface technology, especially when it comes to the analysis and characterization of polymers in coatings and thin films.
