Shodex Columns for Ion exchange chromatography (IEC)

Shodex Size Exclusion Columns for Polymers Chromatography with Organic Solvents

Size Exclusion Chromatography (SEC), also known as Gel Permeation Chromatography (GPC), is a technique used for separating and analyzing macromolecules based on their size.

In SEC, a sample is passed through a column filled with porous beads. Larger molecules elute faster because they can't penetrate the pores, while smaller ones spend more time inside the beads.

Shodex offers a variety of organic GPC columns for SEC with organic solvents like THF or DMF.

Shodex's organic GPC columns cater to various applications, from low to high molecular weight compounds, and comply with USP-NF L21 requirements.
