Brit.

/ˌmas ˈspɛktrəskəʊp/, U.S.

/ˈˌmæs ˈspɛktrəˌskoʊp/

Origin: Formed within English, by compounding. Etymons: mass n.², spectroscope n.

Etymology: < mass n.² + spectroscope n. Compare earlier mass spectroscopy n., mass spectrometer n.

A mass spectrometer.In technical use now less common than mass spectrometer and mass spectrograph.
