Excellent agreement was noted in the concentration of major and trace elements in five NIST soil reference materials (NIST SRM 2586, 2587, 2709a, 2710a and 2711a) between measurement results from wavelength dispersive-XRF and ICP-MS from two independent laboratories, and NIST certificate of analysis and literature data. We describe the variability in concentrations of up to forty-nine elements (plus loss on ignition) and provide values for up to twenty-one elements previously uncharacterised by NIST in these soil RMs. The additional characterisation provided in this investigation can be utilised to reduce the measurement bias of custom calibration routines and improve the quality of control checks developed using these NIST RMs.
在五个美国国家标准与技术研究院（NIST）土壤标准物质（NIST SRM 2586、2587、2709a、2710a和2711a）中，来自两个独立实验室的波长色散X射线荧光光谱仪（WD-XRF）和电感耦合等离子体质谱仪（ICP-MS）的测量结果之间，以及NIST分析证书和文献数据之间，主要和微量元素的浓度呈现出极佳的一致性。我们描述了多达49种元素（加上烧失量）浓度的变异性，并给出了这些土壤标准物质中多达21种NIST此前未表征元素的值。本研究提供的额外表征可用于减少定制校准程序的测量偏差，并提高使用这些NIST标准物质制定的质量控制检查的质量。
