mass spectrometry

(mas spek-trom'ĕ-trē),
The analysis obtained using a mass spectrograph.

mass spectrometry

A method for identifying molecules based on the detection of the mass-to-charge ratio of ions generated from the molecule by vaporisation and electron bombardment. Deflection of the ions through a magnetic field results in a characteristic pattern which is used to define the molecule of interest.
