Morphology

mass + spectrograph

The compound is directly analyzable: 'mass' specifies the type of spectrum and 'spectrograph' is an instrument that records spectra, so a 'mass spectrograph' is readily understood as an instrument that records or separates by mass. This follows a common noun–noun composition pattern (type + instrument) found cross-linguistically, so a learner who knows both constituents can infer the meaning despite the term's technical domain.

Etymology

The name mass spectrograph comes from the parts mass, spectro, and graph: mass is the weight of tiny particles, spectro points to a 'spectrum' (a range), and graph means a 'drawing' or line that shows data. The machine sorts charged particles by their weight and makes that 'spectrum' into a picture, so the name means an 'instrument' that shows which masses are present.
