Original product description
Silica Gel Filter Media-Column Chromatography Silica Gel Detailed Photos Packaging & Shipping In pharmaceutical production, chromatography silica gel is widely used due to its high adsorption, chemical stability, and controllable pore diameter : 1, Separation and purification of active ingredients in traditional Chinese medicine Natural medicine extraction: to separate active ingredients such as alkaloids, flavonoids, saponins, etc.
from traditional Chinese medicine, and meantime to achieve high-purity extraction through adsorption retention time differences. Impurity removal: Remove interfering substances such as pigments and tannins from the extraction solution to improve the purity of the drug.
2, Chemical synthesis drug refining Intermediate purification: Separate and purify intermediates during the synthesis process to remove by-products and residual catalysts.
Chiral Separation: Utilizing the differential adsorption of silanol groups on the surface of silica gel to separate enantiomers (such as chiral drugs).
3, Biopharmaceutical field Peptide and protein purification: Large pore silica gel (such as C-type, pore size>10nm) is used to purify peptides, proteins, and antibiotics with molecular weights ranging from 500 to 40000.
Separation of nucleic acid substances: Purification of biological macromolecules such as oligonucleotides and nucleotides. 4, API Preparation Final product refinement: Remove trace impurities through gradient elution technology to ensure that the raw material meets pharmacopoeia standards.
Solvent residue control: adsorb residual organic solvents (such as methanol, ethyl acetate). 5, Medicinal excipients and carriers Catalyst carrier: an inert carrier used for solid-phase synthesis or catalytic reactions. Drug release materials: Use their porous structure to control the drug release rate.
Key parameters for technical selection : Application Silica gel Specifications Small molecule (≤ 500.
