Chromatography - Wikipedia
https://en.wikipedia.org/wiki/Chromatography
WEBChromatography – a physical method of separation that distributes components to separate between two phases, one stationary (stationary phase), the other (the mobile phase) moving in a definite direction. Eluent (sometimes spelled eluant) – the solvent or solvent fixure used in elution chromatography and is synonymous with mobile phase.

WEBchromatography, technique for separating the components, or solutes, of a mixture on the basis of the relative amounts of each solute distributed between a moving fluid stream, called the mobile phase, and a contiguous stationary phase. The mobile phase may be either a liquid or a gas, while the stationary phase is either a solid or a liquid.

WEBJan 11, 2024 · Chromatography is an analytical technique used to separate a given mixture into its components. The technique is based on the principle that when a mixture and a mobile phase are allowed to flow over a stationary phase, the separation occurs based on the differential affinities of the components for these 2 phases.

WEB10.17.2019. Chromatography is a process for separating components of a mixture. To get the process started, the mixture is dissolved in a substance called the mobile phase, which carries it through a second substance called the stationary phase. The different components of the mixture travel through the stationary phase at different speeds ...

WEBApr 16, 2024 · Chromatography is a method by which a mixture is separated by distributing its components between two phases. The stationary phase remains fixed in place while the mobile phase carries the components of the mixture through the medium being used. The stationary phase acts as a constraint on many of the components in a mixture, slowing …
