Morphology
The compound 'mass spectrometer' is directly interpretable from 'mass' (amount of matter) + 'spectrometer' (an instrument for analyzing spectra/ions): it denotes an instrument for measuring masses. This noun–noun compositional pattern (instrument for measuring X) is cross-linguistically common, so a B1 learner who knows both constituents would readily infer the meaning.
Etymology
Mass spectrometer is named for what the machine does: it sorts tiny charged bits by mass and the spectrometer part makes a 'spectrum' — a clear pattern of those masses. So the name means 'a machine that separates and measures masses' and helps scientists 'identify' what is in a sample.
