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 distances moved by different chemicals in a sample.

Chromatograms can be used to identify chemicals in an unknown mixture by:

Comparing the chromatogram of a sample to the chromatograms of known chemicals.
Calculating the Retention Factor (R_f) of the chemicals in the sample and comparing it to known R_f values.
