Notes:
The conversion of X-ray fluorescence intensities to concentrations by a mini-computer requires simple equations for routine use. The influence coefficients, accounting for inter-element effects in homogeneous samples, are calculated from fundamental parameters by means of a programme called ALPHAS operating on a large computer. These coefficients can subsequently be used in the simple routine equations for wide range calibration. The theoretical coefficients are a valuable support for wide range calibrations using multiple regression analysis. The number of required standards is significantly reduced. The exclusive use of theoretical influence coefficients is demonstrated for stainless steel.
