Lunar Surface' Sputtering and Secondary Ion Mass Spectrometry
We combine laboratory and Apollo year on the moon) every surface species has been observations to describe the sputtering of the struck and subsequent ions eject chemicallylunar surface and the composition of the ejecta altered species. At high fluences sputtering with special reference to O. The atmospheric proceeds stoichiometrically (Johnson 1990). inventory appears to be dominated by microT...
متن کاملMass spectrometry sampling under ambient conditions with desorption electrospray ionization.
A new method of desorption ionization is described and applied to the ionization of various compounds, including peptides and proteins present on metal, polymer, and mineral surfaces. Desorption electrospray ionization (DESI) is carried out by directing electrosprayed charged droplets and ions of solvent onto the surface to be analyzed. The impact of the charged particles on the surface produce...

mental standards, and by statistical and systematic errors in the measurement of x-ray lines and in the separation of line intensity from spectral background. The errors in estimating the characteristics of the detector system, with exception of deadtime effects, cancel when the emission from the specimen is divided by that from the standard. The estimate of achievable accuracy of EPMA and the ...
متن کاملHigh Mass Resolution Plasma Desorption and Secondary Ion Mass Spectrometry of Neutral Nickel Thiolate Complexes. Crystal Structure of [Ni6(SC3H7)12]
The use of mass spectrometry for the analysis of transition metal complexes is demonstrated by combined high resolution Plasma Desorption Mass Spectrometry (PDMS) and Secondary Ion Mass Spectrometry (SIMS) investigations of the neutral nickel thiolate complexes [Ni4(SC3H 7)8] (1 ), [Ni4(SC6H n)8] (2 ), [Ni8(SCH2COOEt)16] (3 ) and [Ni6(SC3H 7),J (4 ). The posi tive spectra are dominated by thre...
متن کاملLiquid Secondary Ion Mass Spectrometry
Liquid secondary-ion mass spectrometry (liquid SIMS) is an obsolescent ionization technique that revolutionized the analyses of large biological molecules in the 1980s. The term includes fast atom bombardment mass spectrometry (FAB-MS). The technique has been largely superseded by electrospray ionization. This account will cover the history of the technique, the principles of the operation, and...
