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.

使用ICP-MS和波长色散XRF在土壤参考材料NIST SRM 2586、2587、2709a，2710a和2711a中测量了49种主要和痕量元素的浓度。

在两个独立实验室的波长色散XRF和ICP-MS的测量结果与NIST的五种NIST土壤标准物质（NIST SRM 2586、2587、2709a，2710a和2711a）中的主要元素和痕量元素的浓度之间达成了极好的一致性分析证书和文献数据。我们描述了多达49个元素的浓度变化（加上燃烧损失），并提供了NIST在这些土壤RM中先前未表征的多达21个元素的值。本研究中提供的其他特性可用于减少自定义校准例程的测量偏差，并提高使用这些NIST RM开发的控制检查的质量。
