“…This material is certified for concentrations of twelve trace elements of potential environmental concern. Other authors have reported further major and trace element analyses (Ondov et al, 1975). It has been pointed out, however, that the bioenvironmental effects of the ash removed by the precipitator may differ substantially from that of the material that escapes (Fisher et al, 1976b).…”

A system is described for rapid, simultaneous three colour elemental mapping with a scanning electron microscope (SEM) and an energy dispersive X-ray analyser. The technique, which use a SEM scanning at TV rate, minimizes the disadvantages of long scan times such as inefficient use of linear amplifer and observable dead-time shadowing. The system also employs a digital scan-stop assembly utilizing a light pen to rapidly and reproducibly direct the beam to an object of choice for spot-mode analysis. Application of the system to analysis of fine particulates with emphasis on fly ash derived from coal-fired electric power plants is discussed. Chemical heterogeneity of fine particles in standard reference material fly ash and in phagocytized fly ash within pulmonary macrophages is demonstrated. This system combines the morphologic capability of the SEM with X-ray multielement mapping to provide a needed tool for particulate source identification.

“…Replicated INAA results for NBS 1632 were published in Gluskoter et al (1977) and Ruch et al (1979). These data compared rather favorably to certified values and results from Ondov et al (1975). However, NBS 1632 has been out of supply for some time.…”

The contributed papers followed by presenting recent experimental results in those areas reviewed in the plenary papers.This conference provided an l!llusual opportunity for attendees with expertise and interests in the diverse areas of atomic analytical techniques and nuclear analytical techniques to communicate together and discuss topics of mutual interest. We feel these discussions were very fruitful and educational for all the attendees and will lead to beneficial collaborations in the future. , members of the Technical Committee.The editors would like to acknowledge the unselfish giving of time and talent of those whose help made this conference a success. We wish to express our added appreciation to the session chairmen for their overall contributions: PREFACE vii son of Washington State University. A special thanks is extended to S. Hendrickson of Lawrence,Livermore National Laboratory for the compilation and preparation of the abstracts.Although proper prearrangements are critical to any meeting, implementation is equally critical. For the invaluable on-site assistance we received during the various phases of the conference, we are indebted to many, but especially to K. B. Pedersen for arranging so much of the local assistance. We are indebeted specifically to the staff of the Center for Energy and Environment Research; S. E. Alemany, Chancellor, University of Puerto Rico -Mayaguez Campus; and M. Vargas-Cesani, Recinto Universitario de Mayaguez. We wish to express our appreciation to D. Bennett, C. Filby and N. Wogman for coordination of all the last minute crises, both before and during the meeting. Finally, we would like to thank R. E. Sinclair, Applied Physics Technology, for organizing the coffee breaks which were sponsored by Canberra, ORTEC, Nicolet, and Nuclear Data.The location of the conference, Mayaguez, Puerto Rico, not only provided an excellent secluded atmosphere for informal working groups to be formed, but also was an equally enjoyable and superb setting for those who accompanied the attendees. The location was surpassed only by the cordiality of the hosts, J. Guzman, H. J. Santiago, J. A. Petrillo and staff, at the Mayaguez Hilton, the conference hotel. Competing with scenery and cordiality of the hotel was the ex...

“…108 As a result of a study of SRM 1632 (coal) by four laboratories using NAA methods, it was found that there were variations in the concentrations of antimony in several samples. 174 This was not an interference effect, but may be due to some inhomogeneity in the samples.…”
