The NBS coal and fly ash Standard Reference Materials (SRM 1632 and 1633) were analyzed for 37 elements in coal and 41 elements in fly ash mainly by the use of instrumental neutron activation analysis (INAA), augmented by instrumental photon activation analysis (IPAA) and direct counting of natural ..gamma..-ray activity. For most elements measured, there was excellent interlaboratory agreement between the four participating laboratories and with the National Bureau of Standards values for elements measured by them and in this work. In cases of most elements for which comparisons can be made, instrumental nuclear methods used in a round-robin study of the standards provided more accurate average concentrations and smaller interlaboratory dispersions of values than the other major techniques used, atomic absorption spectrometry and optical emission spectroscopy.
