Smartdex G-25

Smardex G-25 is a gel filtration medium prepared by cross-linked dextran. Size exclusion chromatography (SEC), also called Gel filtration (GF), separates molecules on the basis of differences in size as they pass through a SEC medium packed in a column. Media for SEC contains spherical particles with pores of different sizes where molecules smaller than the pores are retarded relative to molecules larger than the pores. Samples are eluted by a single buffer without gradients. Buffer conditions can be varied to suit the sample type or the requirements for the next purification, analysis, or storage step.

Smartdex G-25 is well established for desalting, removing contaminants and buffer exchange in industrial applications.
