Cosmosil Diol-II Packed Columns

Click for Application Data

Gel filtration chromatography separates enzymes, proteins and other water- soluble polymers by utilizing the difference in the size of the molecules. Since mobile phases used for gel filtration chromatography are usually moderate buffer solutions or salts, this method can separate molecules while retaining their biological activity. The COSMOSIL Diol-II packed column is highly recommended for the separation of various water-soluble polymers.
