The relationship between the fluorescent intensity ratio of analyte to pure analyte/concentration of analyte and the fluorescent energy can be expressed as In( I i / I i 0 c i ) = a In E i + b , where a and b are constants for a given matrix. This relationship depends on the pure element intensity I i 0 . Experimental pure element intensities can be obtained in a number of ways. Although the use of thick pure metal foils is perhaps the simplest, there are many elements for which pure metal foils are not available. This paper discusses the determination of experimental values of pure element intensities from their oxides and shows that their values are in good agreement with those obtained from pure metal foils.
