==Key Stage 4==
===Meaning===
[[File:ChromatographDiagram2.png|right|300px|thumb|The [[chromatogram]] is on the far right having been produced in a [[chromatography]] [[experiment]].]]
A [[chromatogram]] is the result of a [[chromatography]] [[experiment]] showing the relative [[distance]]s moved by different [[chemical]]s in a [[sample]].
===About Chromatograms===
[[Chromatogram]]s can be used to identify [[chemical]]s in an unknown [[mixture]] by:
*Comparing the [[chromatogram]] of a [[sample]] to the [[chromatogram]]s of known [[chemical]]s.
*Calculating the [[Retention Factor|Retention Factor (R<sub>f</sub>)]] of the [[chemical]]s in the [[sample]] and comparing it to known [[Retention Factor|R<sub>f</sub>]] values.
