- Abstract
This article discusses the use of a jadeite crystal as a reference material for instrument calibration in microanalysis. The researchers used various microbeam methods, including cathodoluminescence imaging and spectrometry, to assess the microscale uniformity of the crystal. They found that the crystal had remarkable uniformity in terms of its major elements, but also contained complex microstructures and chemical inhomogeneity. The study confirmed the presence of trace elements such as Ce3+, Mn2+, and Cr3+ in the crystal, and observed that small increases in Fe concentration correlated with decreases in cathodoluminescence spectral intensities. Overall, the jadeite crystal was deemed suitable for use as a major element reference, but its complex microstructure should be taken into account.
