mass spectrometer in English

noun
1
an apparatus for separating isotopes, molecules, and molecular fragments according to mass. The sample is vaporized and ionized, and the ions are accelerated in an electric field and deflected by a magnetic field into a curved trajectory that gives a distinctive mass spectrum.
The gas chromatograph separates the substances present, and then each substance is broken into molecular fragments by the mass spectrometer .
