Chromatography is an important biophysical technique that enables the separation, identification, and purification of the components of a mixture for qualitative and quantitative analysis.

The Russian botanist Mikhail Tswett coined the term chromatography in 1906.

To identify the unknown sample , its $R_{f}$ value is found which is specific for a compound.

$R_{f} = \frac{d i s \tan c e t r a v e l l e d b y t h e s u b s \tan c e}{d i s \tan c e t r a v e l l e d b y s o l v e n t f r o n t}$
