Properties of Sephadex LH-20 CAS 9041-37-6

Dextran gel/Sephadex LH-20/LIPOPHILIC SEPHADEX refers to a type of gel that is formed by cross-linking dextran and glyceryl groups with a certain average relative molecular weight in the form of ether bridges. It has a three-dimensional network structure and has a wide range of applications. The trade name is Sephadex. The degree of cross-linking can be controlled by controlling the ratio of the cross-linking agent (usually epichlorohydrin) and dextran and the reaction conditions.

Application of Sephadex LH-20 CAS 9041-37-6

Dextran gel/Sephadex LH-20/LIPOPHILIC SEPHADEX is a bead-like cross-linked glucan that contains a large number of hydroxyl groups and is easy to swell in water and electrolyte solutions. G-type dextran gels have various degrees of cross-linking. Therefore, their swelling and fractionation ranges are also different. SepandexG-10 and G-25 sugar gels are used in aqueous solutions. If organic solvents are used as mobile phases, SepandexG needs to be converted into hydroxypropyl dextran gels that can be swelled in organic solvents by hydroxypropylation. 

The product at this time is Sepandex LH-20. Sephadex has different particle sizes. Ultra-fine dextran gels are used for column chromatography and thin layer chromatography that require extremely high resolution. Coarse and intermediate gels are used in laboratory and industrial preparation processes to obtain higher flow rates at lower pressures. Sephadex LH-20 can be used to separate cholesterol, fatty acids, hormones, vitamins, natural products, etc.
