CHROMATOGRAPHY
19.1 INTRODUCTION
The separation of a mixture by the distribution of its components between a mobile and a stationary phase is known as chromatography. Here, the mobile phase is solvent and stationary phase is column packing material.
Chromatography is a valuable analytical tool as it can separate mixture components. It is also a useful technique to obtain qualitative and quantitative information about each component.
The term “chromatography” is applied to a process in which mixture components are separated by differential migration. The differential migration is caused by flow of mobile phase.
It may also be defined as follows:
Chromatography comprises a group of techniques that are used to separate mixture components by the ...
