Molecular weight distribution measurement by GPC

HPLC: High-Performance Liquid Chromatography

GPC (Gel Permeation Chromatography) is one of the separation modes of HPLC and is a method for evaluating the molecular weight of polymer compounds. It can determine several average molecular weights (Mn), weight average molecular weight (Mw), and polydispersity (Mw/Mn) in a single analysis, and it is also possible to compare the distribution profiles. It is also referred to as SEC (Size Exclusion Chromatography).

GPC measurement - Measurement of the molecular weight distribution of resin

GPC measurement - Measurement of the molecular weight distribution of resin

Measurements can be performed with various solvent systems such as toluene-based, cyclohexane-based, and high-temperature systems!

We would like to introduce the "SEC (GPC, APC) analysis" conducted by Ronbic Co., Ltd. Measurements can be performed using various solvent systems such as THF (Tetrahydrofuran), HFIP (Hexafluoroisopropanol), and DMF (N,N-Dimethylformamide). Examples of causes for abnormalities in molded products include insufficient drying of raw materials and abnormal molding conditions, which can lead to a decrease in molecular weight and insufficient strength of the molded products. 【Examples of measurable solvents】 ■ THF (Tetrahydrofuran) ■ HFIP (Hexafluoroisopropanol) ■ NMP (1-Methyl-2-pyrrolidone) ■ Cyclohexane ■ Chloroform ■ DMF (N,N-Dimethylformamide) *For more details, please download the PDF or feel free to contact us.
