Abstract

A quantitative X-ray fluorescence method for single or multielement analysis is reported. It requires no calibration curve and covers a wide concentration range. The sample is dispersed into a film-forming polymer solution from which a thin specimen is made. A simple intensity-concentration equation free from matrix factors is derived. The simplicity and versatility of this method are demonstrated with eighteen examples. The precision of this method is statistically estimated to be 5% relative.
