The Prize was shared with Kurt Wüthrich, who developed nuclear magnetic resonance spectroscopy for determining the 3-D structure of biological macromolecules in solution, a topic that is beyond the scope of the present work. 3.3.3 Mass Spectrometry for Elemental Imaging The first commercial mass ...
Reference work2010,Encyclopedia of Spectroscopy and Spectrometry (Second Edition) Amy V.Walker Explore book Mass Analyzers There are three types of mass analyzer commonly used inSIMS:TOF,quadrupole(QMA/QMS), and double-focusing mass sector. To obtain elemental depth profiles, quadrupole and magnetic ...
Related to mass spectroscopy:NMR spectroscopy n. Any of various devices that use magnetic fields, electric fields, or both to determine the masses of isotopes in a sample by producing a mass spectrum. Two types of mass spectroscopes are the mass spectrograph and the mass spectrometer. ...
The meaning of MASS SPECTROMETRY is an instrumental method for identifying the chemical constitution of a substance by means of the separation of gaseous ions according to their differing mass and charge —called also mass spectroscopy.

The present invention provides a photoionization mass spectroscopy flux monitor for gaseous species above a sample surface. It provides an in situ, real time, species specific, nonintrusive probe with a geometry compatible with conventional MBE growth chambers. Gaseous species are photoionized above a ...
Recently, Raman spectroscopy was proposed for urinary nucleoside screening [45,95]. Despite its poor sensitivity relative to MS, Raman spectroscopy is label free and noninvasive. Low sensitivity may, however, be overcome with surface-enhanced Raman scattering (SERS) with metal nanoparticle adsorption....
