Book Description
The report describes the advances in instrumentation and the research activities of the Analytical Mass Spectrometry Section during the period July 1967 to June 1968.Advances in instrumentation include the construction of the electronic interface automating both the control of the multistage instrument, and the digital readout and data reduction.A new and improved beam valve is also described.Elements studied during this period include: B, Ni, Pb, Li, U, and Pu.Chemical procedures are given for B, Pb, CaF2, U, and Pu; mass spectrometric procedures are given for B.(Author).

Book Description
Excerpt from Analytical Mass Spectrometry Section: Summary of Activities, July 1968 to June 1969 During the year, we have become active in the project for trace characterization by isotope dilution. Uranium, lead, copper and boron have been determined in a Trace Elements in Glass Standard, copper has been determined in a number of iron and steel samples, and lead has been determined in a special Standard Reference Material steel.

Book Description
Excerpt from Analytical Mass Spectrometry Section: Summary of Activities July 1967 to June 1968 The Analytical Chemistry Division was established as a separate division at the National Bureau of Standards on September 1, 1963, and became part of the Institute for Materials Research in the February 1, 1964 reorganization. It consists at present of nine sections and about 100 tech nical personnel encompassing some M5 different analytical competences from activation analysis and atomic absorption to vacuum fusion and x - ray spectroscopy. These competences, and in turn the sections which they comprise, are charged with research at the forefront of analysis as well as awareness of the practical sample, be it standard reference material or service analysis. In addition it is their responsibility to inform others of their efforts. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
The report describes the advances in instrumentation and the research activities of the Analytical Mass Spectrometry Section during the period July 1968 to June 1969.Chemical and mass spectrometric procedures are described for the determinations of the absolute isotopic abundance ratios of natural rubidium, boron in a natural boric acid and a 10B enriched boric acid, and of uranium in six SRMs.Procedures are also described for the determination of trace amounts of copper and lead in steel, and silver, copper, boron and uranium in glass by isotope dilution mass spectrometry.(Author).

Book Description
This is the fifth summary of progress of the Radiochemical Analysis Section of the Analytical Chemistry Division at the National Bureau of Standards. The sections' effort comprises four major areas: Mossbauer spectrometry, nuclear chemistry, nuclear instrumentation and the application of statistics in nuclear and analytical chemistry. Studies in nuclear reactions have centered around measurement by time of flight mass spectrometry of helium-4. Statistical methods have been applied to the measurement of peaks in radiation spectra, to reporting trace amounts of radioactivity, to the calibration of Standard Reference materials, and to the reporting of detection limits of a system of measurement. A procedure for cooling a moving absorber with a stationary source for Mossbauer spectrometry is described. Theoretical interpretations of Mossbauer spectra of nickel compounds are given. Several applications of Mossbauer spectrometry, such as surface corrosion studies are described. Preliminary data are given on the charge states of 119mSn after nuclear recoil. An overflow counter for collecting more counts than the memory capacity of a pulse height analyzer is described.

Book Description
Excerpt from Analytical Mass Spectrometry Section: Summary of Activities, July 1966 to June 1967 This Technical Note has been written in an entirely different vein than Technical Note 277. The intent of the first Technical Note (277) was to define our position after 8 years of effort and is truly more of a cook book or operating manual than anything else. This Technical Note is intended as a summary of our effort for the fiscal year of 1967. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
