Sephadex LH-20 - Physico-chemical Properties
| Molecular Formula | C9H8N2O3S |
| Molar Mass | 224.23642 |
| Storage Condition | Room Temprature |
| Use | Use biochemical research. Dextran gel is a bead-like cross-linked dextran that contains a large amount of hydroxyl groups and is easy to swell in water and electrolyte solutions. G-type dextran gels have various degrees of crosslinking. Therefore, their swelling and fractional separation ranges are also different. Sepandex G-10 and G-25 sugar gels are used in aqueous solutions. If an organic solvent is used as the mobile phase, Sepandex G needs to be converted into hydroxypropyl dextran gels that can swell in organic solvents through hydroxypropylation. The product at this time is Sepandex LH-20. Dextran gels have different particle sizes. Ultrafine grade dextran gels are used for column and thin layer chromatography that require extremely high resolution. Crude and intermediate gels are used in laboratory and industrial preparation processes to obtain higher flow rates at lower pressures. Dextran gel LH-20 can be used to separate cholesterol, fatty acids, hormones, vitamins, natural products, etc. |

Sephadex LH-20 - Introduction
sephadex(R) LH-20 for chromatography is a packing used in chromatographic separations, also known as Sephadex(R) LH-20. It is cross-linked by dextran (Dextran) and 2,3-dimethyl digitalis digitalis digitalis glycoside (Digitoxin). Its main features include:
1. High porosity and porosity: sephadex(R) LH-20 for chromatography has a large number of pores, which makes it able to adsorb target substances and effectively separate them in chromatography.
2. wide applicability: sephadex(R) LH-20 for chromatography is suitable for various chromatographic techniques, such as gel chromatography, gel permeation chromatography and ion exchange chromatography. It is often used for the purification and separation of natural products.
3. Low background: sephadex(R) LH-20 for chromatography has a high adsorption capacity, but the background signal is low, making the separation results more accurate.
The method for preparing sephadex(R) LH-20 for chromatography is to first prepare dextran and conduct a cross-linking reaction with 2,3-dimethyl digitalis digitalis digitalis glycoside. The cross-linked product is then comminuted and prepared into a form suitable for chromatographic operations.
For safety information, the following are general considerations:
1. Avoid contact with skin, eyes or respiratory system. Please wear personal protective equipment such as gloves, glasses and masks when using.
2. During operation, avoid inhaling or swallowing the substance. The working environment should be well ventilated to avoid dust generation.
3. When storing, please store the sephadex(R) LH-20 for chromatography in a dry, cool and dark place, avoiding high temperature and fire.
