| Abstract: | By using easy rock characteristics of S element, and active metal iodide generated by NH4I and sample matrix, response intensity of electrode samples has been intensified, evaporation behavior of all elements have been changed, various analytical element concentration in arc plasma have been increased, and evaporation of tungsten, molybdenum with high boiling point and silver, tin, boron with low boiling point have been buffered well. As showed by many experiments, precision and accuracy of this method can meet the need of analysis. |
