Chromatography is a laboratory technique for separating compounds within a mixture, first devised in Russia in 1900 by Mikhail Tsvet. There are two phases of chromatography – the mobile and ...

It is classified into two types based on the physical state of the mobile phase used – liquid chromatography (LC) and gas chromatography (GC). Chromatography includes a series of procedures that ...

Chromatography works by distributing the components of a mixture between two phases, known as the stationary phase and the mobile phase. Liquid chromatography uses a liquid mobile phase, with the ...

Two substances are likely to be the same if ... R f values vary from 0 (the substance is not attracted to the mobile phase) to 1 (the substance is not attracted to the stationary phase).
