Meaning
A chromatogram is the result of a chromatography experiment showing the relative distances moved by different chemicals in a sample.
About Chromatograms
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 (Rf) of the chemicals in the sample and comparing it to known Rf values.
