X-Ray fluorescence analysis.
Methods of Air Sampling and Analysis, 3rd edition, 1989:218-223
The use of X-ray fluorescence (XRF) analysis in elemental analysis was described. The method was convenient due to the lack of sample preparation, speed of analysis, indifference to the chemical state of the analyte element, and nondestruction of the sample. The XRF method was applicable to all elements beyond the first row of the periodic table, in bulk, liquid or filter samples. This review discussed the theory and operational principles, sampling, analysis, standardization methods, and detection limits for the XRF method. The authors suggest that the increased interest in atmospheric and industrial pollution will result in a greater use of XRF analysis. With the introduction of computer operated instrumentation, the severity of a number of experimental difficulties has been mitigated, such as particle size, overlapping XRF lines and interelement effects, and has greatly shortened the analysis time.
