Morphology

chromatogram = chromatography (semi-transparent) = chromato + gram

The word is built from the combining form chromato- (relating to chromatography/color) + -gram (a record), which is interpretable by learners familiar with 'chromatography' or the suffix '-gram' but the combining forms are not standalone common words.

Etymology

Chromatogram comes from the Greek root chroma meaning 'color' and the ending -gram meaning 'a written record'. So a chromatogram is like a 'color record' or picture that shows the different parts of a mixture after they are separated.
