| Abstract: | The authors consider only interelement effects with the implicit assuption that other possible sources of error have been minimized.The relationship between the measured X ray intensity and the concentration be expressed by linear and Lucas Tooth Pyne mathematical models.The interaction coefficients are determined by a least squares fit of standards concentration intensity data with the IBM 486 computer.Finally,authors discuss the two sets of results. |
