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 ...
