Category : Spectrum analysis

Pages : 112
Book Description
Activities in optical spectrometry included development of programs for calculations on a time-sharing computer, measurement of arc temperatures, applications of the laser probe and the plasma jet, and studies on atomic absorption spectrometry. In x-ray spectroscopy, there were some modifications of equipment, improvements in computation methods, and several applications. Improvements and additions were made to the electron probe analyzer, along with studies on measurement techniques, including nondispersive analysis and computation procedures. The spark-source mass spectrometer was also modified, and a new analog computer has been built and tested for reduction of photographic plate data; applications of this instrument to analyses of pure materials are described. Enrichment methods are being studied for the analysis of pure materials by emission spectroscopy, particularly with an electro-deposition technique. Homogeneity studies and analyses were performed in the development of standard reference materials. (Author).

Book Description
This book describes both the theory of atomic spectroscopy and all the major atomic spectrometric techniques (AAS, Flame-AES, Plasma AES, AFS, and ICP-MS), including basic concepts, instrumentation and applications. Spectrochemical Analysis by Atomic Absorption and Emission is very wide in scope and will be extremely useful to both undergraduates and lecturers undertaking modern analytical chemistry courses. It contains many figures and tables which illuminate the text, covers various sample preparation methods and gives suggestions for further reading.

Book Description
Spectrochemical research activities, improvements in equipment, and applications, especially to the certification of NBS Standard Reference Materials, are summarized. In electron probe microanalysis, a comprehensive computer correction program for accurate analysis of materials relative to single elements or simple compounds was developed, an improved lithium-doped silicon detector was found to provide increased resolution, and improvements in microprobe instrumentation produced a high level of stability. Studies of procedures for correction of x-ray fluorescence measurements were made, instrumental changes resulted in marked improvement in performance reliability, and new applications were made. In optical emission spectrometry, studies were made of beryllium determination in an air pollution investigation and trace analyses were made of organic materials to parts per billion limits. Methods of pre-concentration of impurities are described for optical emission and isotope dilution spark source mass spectrometric analysis of ingot iron, botanical materials, and high purity reagents. Work on Standard Reference Materials resulted in certification of stainless steel, clays, ferrosilicon, blast furnace irons, white irons, lead bearing metal, and ductile irons. (Author).
