Morphology
The meaning 'the process of determining chemical components' is directly and compositionally derived from 'chemical' (relating to chemistry) + 'analysis' (systematic examination). This noun phrase follows a clear and cross-linguistically common modifier + head pattern, so a B1 learner who knows both constituents will readily infer the intended meaning.
Etymology
Chemical analysis comes from the simple idea of taking a substance apart to see what is inside. It joins chemical, meaning a substance, and analysis, meaning examining or separating things, so it means testing a material to find its parts or 'find what is inside'.
