WebAug 15, 2024 · In gas chromatography, the components of a sample are dissolved in a solvent and vaporized in order to separate the analytes by distributing the sample between two phases: a stationary phase and a mobile phase. The mobile phase is a chemically inert gas that serves to carry the molecules of the analyte through the heated column. 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. Let's go over how paper chromatography works, since this is the simplest kind.
