Excerpt from Microchemical Analysis Section: Summary of Activities, July 1965 to June 1966 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 I, 1964, reorganization. It consists at present of nine sections and about 100 technical personnel encompassing some 45(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.
