Theory and experimental results from X‐ray fluorescence analysis without standards are presented. The composition of an unknown specimen is calculated from its count rates without the use of standard specimens. A fast algorithm employing linear approximation techniques uses these normalized count rates as start values for the concentrations and delivers final results usually after the second or third iteration. Accuracy is typically around 10% relative and can be improved by system calibration with standards of arbitrary composition.
