5. Practical application examples of column chromatography silica gel5.1 Study on the separation of Lanzhou red radish pigments by thin layer chromatography and column chromatography.Thin layer chr...

3. Column selectionCommonly used columns can be divided into: pressurized, normal pressure, and reduced pressure.Pressure can increase the flow rate of the solvent and reduce the time for product c...

Chromatography, also known as chromatography. It is a distribution method based on distribution equilibrium as the mechanism. The chromatography system contains two phases, one is the stationary ph...

Silica gel is one of the commonly used materials in desiccants. Let’s talk about how to reuse silica gel desiccants. There are three points to pay attention to:1. Regeneration of silica gel after a...

The raw material of early air separation water-resistant silica gel was finished silica gel or crushed rubber, which was obtained after mixing and processing with silica sol. Japan has been industr...

Column chromatography can be divided into: pressurized, normal pressure, and reduced pressure according to the pressure when passing through the column. Pressure can increase the flow rate of the e...

Sample loading can also be divided into wet method and dry method:The wet method generally uses eluent to dissolve the sample, and can also use methylene chloride, ethyl acetate, etc., but the less...

Column packing for column chromatography is very important, and the effect of column packing will directly affect the chromatographic separation effect. When packing a column (adding silica gel), t...

Extraction, isolation and characterization of small biological molecules from natural products is one of the main ways to obtain lead compounds in the development of new drugs. Chromatography is on...

Column chromatography silica gel is divided into two types: normal phase column chromatography silica gel and reverse column chromatography silica gel. The normal phase column chromatography silica...

In organic experiments, when a mixed sample containing a variety of organic compounds cannot be recrystallized, column chromatography on silica gel can be said to be an effective separation method....

Column chromatography is the ideal method of chromatography for purification and separation. It is a technique in which the stationary phase is solid adsorbents like silica gel and activated alumin...

The silica gel packets – also referred to as desiccant packets or dry packets – do not expire. They are made from a material that will not expire or go bad.But as the silica gel packets are exposed...

Desiccants are still common in our daily life. No matter what products, especially bag packaged products, have desiccants, which are used to protect their products from moisture. Can desiccants be ...

a) Specific surface: refers to the surface area per gram of silica gel, including the sum of internal microporous surface area and external surface areaUnit: m2/gb) Pore volume: the total volume of...

The main component of silica gel is silicon dioxide, whose molecular formula is usually expressed as SiO2 · nH2O, which is a material with complex pore structure. Silica gel is widely used as adsor...

Molecular sieve is a kind of aluminosilicate, which is mainly composed of silica alumina through the oxygen bridge to form an open framework structure. In the structure, there are many holes with u...

Application of silica gel powder in column chromatographyAccording to the excellent performance of silicone powder shared by column chromatography, its wide application scope is determined. It is n...

Chromatographic column is the main component of high performance liquid chromatograph, and the column efficiency directly affects the analysis and detection of target compounds. However, in HPLC an...

Inner diameter of sieve( μ m) ≈ 14832.4/mesh size:The particle size of the unit of measurement refers to the size of the raw material particles, which is generally expressed by the diameter and len...
