What is Chromatography?And churning?

Answer 1

A Mixture of Colors. ... Figure 1: A liquid moves through a finely divided solid, and a mixture placed at the top gradually separates into its component parts as it moves along. Since then,chromatography has become a cornerstone of separation science, that branch of chemistry devoted to separating compounds from mixtures

Answer 2

Chromatography is a laboratory technique for the separation of a mixture. The mixture is dissolved in a fluid called the mobile phase, which carries it through a structure holding another material called the stationary phase. The various constituents of the mixture travel at different speeds, causing them to separate. The separation is based on differential partitioning between the mobile and stationary phases. Subtle differences in a compound's partition coefficient result in differential retention on the stationary phase and thus affect the separation.[1]

Chromatography may be preparative or analytical. The purpose of preparative chromatography is to separate the components of a mixture for later use, and is thus a form of purification. Analytical chromatography is done normally with smaller amounts of material and is for establishing the presence or measuring the relative proportions of analytes in a mixture. The two are not mutually exclusive.[2]
