Abstract
A Si(Li) X-ray fluorescence system makes simultaneous determination of Fe, Rb, Sr, Y, Zr, Nb, and Mo in rock powders possible. Standard pulverized samples, including U.S. Geological Survey standards, ranging from ultrabasic to syenitic composition were used to calibrate the system. Detection limits of 10 to 20 ppm for the elements Rb through Mo were estimated. Precision and accuracy of the method are generally better than 10%.
