In the alloy manufacturing and die-casting industry, the chemical composition of raw materials and finished products is one of the most important factors in providing high-quality products. To obtain accuracy data, spark optical emission spectrometry (SPARK-OES), inductively coupled plasma atomic emission spectrometry (ICP-OES) and, increasingly, portable X-ray fluorescence spectrometry (XRF) are commonly used in the industry for composition testing. What are the advantages and disadvantages of each assay and its cover range?
