In chromatography, what is the pattern formed on an adsorbent medium called?

In chromatography, the pattern formed on an adsorbent medium is referred to as a chromatogram. This term describes the series of spots, bands, or zones that represent the different components that have been separated during the chromatography process. Each component moves at a different rate through the medium due to variations in their affinities for the stationary phase and the mobile phase, leading to distinct patterns.

To clarify, an electropherogram pertains specifically to the results of electrophoresis, which is a different technique used to separate charged molecules. A photogram relates to images created by light, often in photography, and a spectrogram is associated with the display of a spectrum of frequencies, typically in the context of sound waves or electromagnetic radiation analysis. Each of these terms describes specific techniques or visual outputs that are not applicable to chromatography, further reinforcing why "chromatogram" is the correct and relevant term in this context.
