This book was released on 1968 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analytical sensitivity of an x-ray fluorescence spectrometer utilizing a radioisotope exciter source and a high-resolution, lithium-drifted silicon detector was evaluated. The spectrometer system which was studied used I125 as the exciter source and contained a 30 sq mm detector with a resolution of 512 eV full-width at half-maximum (FWHM) at 6.40 keV. Known molybdenum samples ranging from 10 nanograms to 1 milligram and nickel samples ranging from 0.1 microgram to 1 milligram were prepared and analyzed. It was found that the detection limit for molybdenum was 35 nanograms with a ca 5 mc exciter source; precision in the submicrogram range was 10-20%. The detection limit for nickel was considerably poorer and was found to be 1 microgram for an exciter source strength of ca 10 mc. An examination of the various factors that affect the analytical sensitivity of the system showed that the sensitivity was limited primarily by (1) poor detector geometry resulting from the small size of the high-resolution Si(Li) detector, and (2) background. A principal contributor to background was backscatter of the exciter source radiation by materials surrounding the source and detector. It was found that the radiation was being scattered mainly by air. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Environmental Sampling and Analysis A fully reworked and updated introduction to the fundamentals and applications of environmental sampling and analysis Environmental sampling and analysis are essential components of environmental data acquisition and scientific research. The acquisition of reliable data with respect to proper sampling, chemical and instrumental methodology, and QA/QC is a critical precursor to all environmental work. No would-be environmental scientist, engineer, or policymaker can succeed without an understanding of how to correctly acquire, assess and use credible data. Fundamentals of Environmental Sampling and Analysis, 2nd edition provides this understanding, with a comprehensive survey of the theory and applications of these critical sampling and analytical tools. The field of environmental research has expanded greatly since the publication of the first edition, and this book has been completely rewritten to reflect the latest studies and technological developments. The resulting mix of theory and practice will continue to serve as the standard introduction to the subject. Readers of the second edition of Fundamentals of Environmental Sampling and Analysis will also find: Three new chapters and numerous expanded sections on topics of emerging environmental concerns Detailed discussion of subjects including passive sampling, Raman spectroscopy, non-targeted mass spectroscopic analysis, and many more Over 500 sample problems and solutions along with other supplementary instructional materials Fundamentals of Environmental Sampling and Analysis is ideal for students of environmental science and engineering as well as professionals and regulators for whom reliable environmental data through sampling and analysis is critical.
