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.

2024年12月20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.

2019年10月17日 · 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.

2024年1月11日 · In pharmacology, chromatography is used to estimate the purity and potency of drugs. Chromatography can analyze environmental samples for drugs, toxins, and pollutants and help discover many new biomolecules, providing insights into …

What is Chromatography? Chromatography is the technique for the separation, purification, and testing of compounds. The term “chromatography” is derived from Greek, chroma meaning, “colour,” and graphein meaning “to write.”

2024年5月7日 · Chromatography is an important biophysical technique that enables the separation, identification, and purification of the components of a mixture for qualitative and quantitative analysis. The Russian botanist Mikhail Tswett …

Chromatography is an important biophysical technique that enables the separation, identification, and purification of the components of a mixture for qualitative and quantitative analysis.

2024年4月16日 · 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.

2023年8月17日 · Chromatography is the separation of mixtures by distribution between two or more immiscible phases. In chemical laboratories, where it is used for analysis, isolation, and purification, chromatography is the most used separation technique. It is also frequently used in the chemical process industry as a part of small and large-scale production.

Chromatography is used to analyze mixtures by identifying the components, determining the amount of each present, and in some cases, purifying the separate parts. This presentation will provide a brief overview of the basic principles of liquid chromatography, with demonstrations using food dyes.
