Root Explanation

Chromatograph → It is formed from "chroma" (from Greek "chroma", meaning color) and "graph" (from Greek "grapho", meaning to write or record). The word describes a device that records or writes the colors of substances, typically used in separating mixtures.

Memory Tip

Think of 'color' ('chroma') being 'written' or 'recorded' ('graph') — that's what a chromatograph does.
