| Abstract: | The automated semiquantitative direct-current-arc spectre-graphic method was used to analyze 62 elements in eight Argonne Premium Coal Ash samples. All eight coal ash samples were analyzed in triplicate to verify precision and accuracy of the method. The precision for most elements was within ??10%. The accuracy of this method is limited to +50% or -33% because of the nature of the standard curves for each of the elements. Adjustments to the computer program were implemented to account for unique matrix interferences in these particular coal ash samples. |
