Trace Elements and Isotopic Analysis of Natural Samples
Автор:Ramadan A. Mohamed and Hosam El-Din M. Saleh Год: 2013 Издание:LAP Lambert Academic Publishing Страниц: 176 ISBN: 9783659357329 Laser Ablation attached to inductively coupled plasma mass spectrometry (LA-ICP-MS) is widely accepted as a rapid and sensitive technique for trace element analysis of solid materials. Three different instruments are used: 1- a-The double focusing ICP-MS (JMS-PLASMAX2) is used for the analysis of rare earth elements in minerals as (monazite), and for rocks as (standard samples BCR-2, AGV-2), Also lead and strontium isotope ratios in tourmaline sample solution. b- A quadrupole (ELAN6000, Perkin Elmer) mass spectrometer. It was applied for the analysis of single grains of tourmaline sample for Sr and Pb isotope ratios and fused pellets for trace elements composition for different samples 2- Energy dispersive Scanning Electron microscope used for the analysis of zircon fused pellets and single grains. Rutherford back scattering spectrometer for the analysis of zircon fused pellets to ensure the homogeneity of the fused pellets, and LA-HR-ICP-MS (PLASMAX2) for trace elements in...
