Abstract
Equations are presented for obtaining greatest precision from available counting time, and minimum counting time for a specified precision in quantitative x-ray spectroscopic analyses. The equations are derived for analytical situations involving determination of the net peak intensity of a line above background and the ratio of the net peak intensities of two lines above one and two backgrounds. Graphical solutions are provided for some of the equations.
