Reagent class
The small molecule removal device uses the principle of molecular sieve chromatography or exclusion chromatography, and uses the molecular sieve action of a gel with a network structure to separate substances according to different molecular sizes. The packing in the chromatography column is some inert porous network structure substances, mostly cross-linked polysaccharides (such as dextran or agarose). Small molecules can enter the inside of the column and have a long way to flow down, while large molecules are excluded from the outside and have a short way down. When a mixed solution passes through the gel filtration chromatography column, the substances in the solution can be screened according to different molecular weights.
