Glass chromatography columnIn chemical analysis, it is an important separation and purification tool, whose core function is to achieve the separation of components in complex mixtures through physical or chemical interactions.

　　Glass chromatography columnTypical application scenarios:

Organic compound separation

Natural product extraction: isolate active ingredients such as alkaloids, flavonoids, terpenes, etc. from plants and microorganisms.

Purification of synthetic products: Removing by-products, catalyst residues, or unreacted raw materials from organic synthesis reactions.

Chiral compound separation: Separation of enantiomers using chiral stationary phases (such as cellulose derivatives).

Inorganic ion analysis

Ion exchange chromatography: Separation of metal ions (such as Cu ² ⁺, Fe ³ ⁺) or anions (such as Cl ⁻, SO ₄ ² ⁻), commonly used in environmental water samples or mineral analysis.

Chelation chromatography: using metal chelating agents (such as IDA, NTA) to separate specific metal complexes.

Polymer and macromolecule analysis

Gel permeation chromatography (GPC): separate polymers (such as proteins and polysaccharides) according to the molecular size, and determine the molecular weight distribution.

Size exclusion chromatography (SEC): Separate biomolecules such as proteins and nucleic acids to avoid denaturation.

Drug and impurity analysis

Purity testing of drugs: separating active ingredients from degradation products, isomers, or solvent residues.

Extraction of effective ingredients from traditional Chinese medicine: such as separating baicalin, ginsenosides, etc. from traditional Chinese medicine.
