mass spectrometry

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

mass spectrometry

(in chemistry) a technique for the analysis of a substance in which the molecule is subjected to bombardment by high-energy electrons or atoms to cause ionization and fragmentation to give a series of ions in the gas phase that constitutes the fragmention pattern observed by using a mass spectrometer. A molecule can frequently be identified just on the basis of its mass spectrum. See also spectrometry, spectrophotometry.

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.

mass spectrometry (MS) (mas' spek·trˑ·n·mē),

n a method of identifying and analyzing substances by fragmenting substances with a bombardment of high-energy electrons. Each molecule has a specific pattern of fragmentation, and these patterns are recorded on a mass spectrum. This technique is often combined with gas-liquid chromato-graphy.
