26: Introduction to Chromatographic Separations
Chromatography provides a solution to the analysis of complex samples by providing a way to separate the individual species in a sample prior to their analysis by a spectroscopic or electroanalytical method of analysis. In this chapter we provide a general introduction to chromatographic separations.
Chromatography: Definition, Principle, Types & Applications
2023年8月17日 · The separation technique of chromatography is dependent on the principle of partitioning the constituent components between two phases – a Mobile Phase and a Stationary Phase. The mobile phase is used to indicate the mixture of the substances to be separated and dissolved in a liquid or a gas.

2022年8月11日 · Column chromatography is the separation technique where the components in a mixture are separated on the basis of their differential adsorption with the stationary phase, resulting in them moving at different speeds when passed through a column.

2024年1月11日 · 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.[1]
Chromatography - Wikipedia
In chemical analysis, chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed.

Four separation techniques based on molecular characteristics and interaction type use mechanisms of ion exchange, surface adsorption, partition, and size exclusion. Other chromatography techniques are based on the stationary bed, including column, thin layer, and paper chromatography.

2024年11月4日 · Chromatography, 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. Learn more about chromatography in this article.
"Chromatography is a physical method of separation in which the components to be separated are distributed between two phases; one of which is stationary (stationary phase) while the other moves in a definite direction (mobile phase)". Chromatography derives its name from two Greek words as; (chroma) meaning "color" and (graphy) meaning "writing".
