Chromatography

Chromatography is a technique for the purification and separation of molecules in the laboratory.

Examples of common chromatography methods include: ion exchange chromatography, size exclusion chromatography, affinity binding chromatography and hydrophobic interaction chromatography.
Types of chromatography include: two-dimensional chromatography, thin layer chromatography (TLC) and paper chromatography.

Without chromatography, and the work of Banting, Best and a biochemist called Collip (who perfected the purification), we would have no treatment for type I diabetes, that is, insulin would not have been discovered. Without chromatography we wouldn’t be able to sequence DNA, perform PCR, and many drugs and biological mechanisms would not have been discovered.
