High performance liquid chromatography

Liquid/Solid

Qualitative and quantitative analysis

Gas-liquid chromatography (GLC)

Gas/Liquid

Qualitative and quantitative analysis

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.
