摘要：

A new absorption correction applicable to EDX spectra of ionic compounds (oxides, ceramics, minerals,...) is presented. The method enables the accurate quantification of oxygen and nitrogen, and does not require parameters such as specimen thickness, X-ray take-off angle and specimen density. Physically this new correction procedure is based on the sole principle of electroneutrality of the specimen: this means that the sum of all anions and cations times their respective valence states must cancel out. An additional benefit of this method is the possibility to calculate the average thickness of the analysed area if, after the quantitative analysis, numbers for. the specimen density and X-ray take-off angle are available.
