# Study of the molar mass of polymers in the laboratory

## You wish to study the molar mass of polymers

First of all, the study of the molar mass of polymers is carried out by means of the GPC/SEC technique

Indeed, the [Gel Permeation Chromatography (GPC), also called Steric Exclusion Chromatography (SEC)](https://filab.fr/en/our-technical-resources/laboratory-analysis-gpc-sec.md), is a technique allowing the determination of the average molecular masses as well as the distribution of the molar masses of polymers.

Moreover, by associating a series of detectors (RI and UV concentration, RALS/LALS light scattering, viscometer), the GPC/SEC technique allows to determine with accuracy the molecular weight and size but also the intrinsic viscosity and the structure of polymers.

Consequently, GPC/SEC allows through the study of the molar mass of polymers to access data such as the degree of polymerization or the dispersity.

Thus, only a laboratory equipped with GPC/SEC and competent in [polymer analysis](https://filab.fr/en/our-services/our-analysis-services/polymer-materials-analysis-laboratory/laboratory-material-testing/laboratory-polymer-characterization/) is able to meet your needs for the study of the molar mass of polymers.
