内容記述 |
【High-energy synchrotron radiation X-ray fluorescence analysis with microbeam (SR-µXRF) is excellent for the detection of heavy metals and provides elemental imaging corresponding to the tissue microstructure, so we have been working on trace element analysis of bone tissue. In the case of bone tissue, there is a possibility that the quantitative evaluation of trace elements may include additive values from high matrix elements such as calcium and phosphorus. In this study, we prepared analytical standards[1] for quantitative analysis of iron and zinc in rat femur and investigated the effect of matrix on quantitative evaluation. The calibration curves obtained from the analytical standards showed high linearity, and the limits of quantification for iron and zinc were 1.66 μg/g and 0.56 μg/g at 10-second counting. The detection of zinc in bone tissue was not enhanced by the high-matrix component. For iron, the addition of high-matrix components was 2.29 ± 3.24% in the range of 5-500 μg/g, and the maximum addition was about 7%. These trace elements were not significantly affected by high matrix in this method. Elemental images in rat femur are also reported.References:[1] Y. Kato et al., Microchem. J. 207 (2024) 112278. |
