Chromatography works on the principle that different compounds will have different solubilities and adsorption to the two phases between which they are to be partitioned. Thin Layer Chromatography (TLC) is a solid-liquid technique in which the two phases area solid (stationary phase) and a liquid ...

Chromatography is a process for separating components of a mixture. ... The different components of the mixture travel through the stationary phase at different
Column chromatography is a laboratory technique that separates and isolates compounds and active ingredients. It uses a stationary phase such as silica and alumina to separate the components of the mobile phase. The technique utilizes the principle of affinity of the components to ...
