Experimental Studies in EDXRF on a New Linear Relationship for Fluorescence

Volume 48, Number 11 (Nov. 1994) Page 1394-1398

Yap, C.T.; Hua, Younan

An experiment was carried out to verify a previously described linear relationship between ln(fluorescent intensity ratio of analyte to pure analyte/concentration of analyte) and ln(fluorescent energy) or, mathematically, ln(Ii/ciIi0 = a ln(Ei) + b. The best fit to our experimental data for elements from manganese to molybdenum for porcelain matrix is given by ln(Ii/ciIi0 = 2.401 ln(Ei) - 8.701 with a value of the gradient in agreement with the theoretical prediction.
