Figure 8.9 Third stage of SIM. The sections of the creep modulus curve are shifted parallel to the time axis to produce a single continuous curve. Small corrections are applied to allow for fibre shrinkage and for the thermal history of the material. Figure 8.9 Third stage of SIM.

The history of SIMS began with the father of mass spectrometry, J. J. Thomson [4], who reported the emission of secondary Canalstrahlen when primary Canalstrahlen strike against a metal plate. Further studies on secondary ion phe-... [Pg.159]

Early in the history of mass spectrometry (MS), large biomolecules were not analyzed because efficient methods to transport these molecules into the gas phase were unknown. Degradation typically occurred during vaporization of these nonvolatile molecules so that electron ionization of the intact molecular ion was not possible. Ionization by fast atom bombardment (FAB), field desorption (FD), secondary ionization mass spectrometry (SIMS), and plasma desorption (PD)" from the radioactive decay of Cf finally made the ionization and analysis of peptides possible. These latter techniques, although still used today, are not as popular as electrospray... [Pg.72]

The goal of these studies is to link the paragenesis of these (and other) phases to events in a rock s history which, when combined with texture-sensitive geochronology (e.g., SIMS, LA-ICP-MS, and EMP), will enable the determination of the time of these events. These data will allow direct inferences of fundamental tectonic parameters such as the duration of metamorphic events, the duration of melting in the crust, the rates of heating/cooling and burial/exhumation of orogenic belts, and the time and duration of hydrothermal activity. [Pg.331]

The interactions of ions with surfaces have many important applications that include sputter cleaning, ion implantation, ion etching, and surface chemical analysis (SIMS and ISS) [56, 61,64, 84, 117, 129-133]. Discuss each of these processes and by reviewing recent papers in the literature describe a case history of the application of each of these processes. Theories of high-energy ion-surface interactions have been proposed. Discuss the various models that explain the phenomena. [Pg.354]

The advent of laser ablation MC-ICP-MS technology allows the rapid in situ determination of the stable isotope ratios of heavy metals commonly found in sulfide ore deposits (e.g., Cu, Zn, Fe, Sb, Ag) providing important information on the source, transport, and depositional mechanisms of these metals. Pb, Pb, and Pb are formed as the end product of radioactive decay and the isotopic variability of lead results because the elements from which the isotopes form were not evenly distributed in ore bodies. Hence, the analysis of stable lead isotopes in annually laminated lake-sediments is a useful method to study lead pollution history as the relative contribution of pollution and natural lead in sediment samples can be calculated. The analysis of lead isotopes by SIMS has also been used to identify the geographical origin of bullets. [Pg.2404]
