Product description:
Column chromatography, also known as adsorption chromatography. A column is first filled with an insoluble matrix to form a stationary phase, the sample is added to the column and then eluted with a special solvent, and the solvent forms the mobile phase. During the process of elution of the sample from the column, different components are separated one by one through repeated distribution according to the different distribution coefficients of the components in the mixture in the stationary direction and in the mobile phase.
The separation principle of silica gel chromatography is to separate substances according to their different adsorption forces on silica gel. Generally, substances with higher polarity are easily adsorbed by silica gel, and substances with weaker polarity are not easily adsorbed by silica gel. The whole chromatography process is the process of adsorption, desorption, re-adsorption, and re-desorption.
According to different filling matrix and sample distribution exchange principle, ion exchange chromatography, gel filtration chromatography and affinity chromatography are three classical chromatography techniques for separating mixtures.
