Types of chromatography- Purification of organic compounds
Depending on the nature of the stationary and the mobile phases, the different types of chromatographic methods generally used are in a given table,
Column chromatography or adsorption
Liquid/Solid
Large scale separations
Thin-layer chromatography
Qualitative analysis (identification and characterization of organic compounds)
High performance liquid chromatography
Qualitative and quantitative analysis
Gas-liquid chromatography (GLC)
Gas/Liquid
Partition chromatography or ascending paper chromatography
Liquid/Liquid
Qualitative and quantitative analysis of polar organic compounds (sugars, α-amino acids and inorganic compounds)
It is constant for a specific substance (component) within a given set of conditions. Hence, it is possible to identify the several components by determining their Rf values.
