WebAug 15, 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. WebChromatography involves taking some kind of mixture and using either solid or liquid to separate it out into its different parts. There are many different kinds of chromatography, but they all rely on having a mobile phase and a stationary phase.
