Morphology
chromatograph = chromato + graph
The word is built from classical combining forms chromato- and -graph, which are not transparent to an average B1 learner, so the meaning is not easily predictable from the parts.
Etymology
Chromatograph comes from the Greek parts chroma 'colour' and graph 'write', like the chroma in chrome and the graph in autograph. Early scientists used it to pull apart colours in plants into bands on paper, so a chromatograph is a machine that separates and 'writes' the different parts of a mixture, often as coloured bands.
