Multielemental Analysis of Soils using ICP-MS after Microwave-assisted Digestion

This technical report presents a validated method for the multielemental analysis of soils utilizing microwave-assisted digestion and ICP-MS, compliant with HJ 766 and ISO 14869 standards. The report outlines the challenges associated with soil analysis, including matrix effects and the need for accurate quantification of elements. The methodology involves using the speedwave XPERT system for sample digestion and the PlasmaQuant MS for multielemental analysis. Key analytical parameters such as low detection limits and high accuracy are emphasized to ensure reliable results. The report details the instrument settings, sample preparation, and calibration procedures used in the analysis. It also discusses the expected interferences and the methods employed to mitigate them. The findings are supported by method detection limits and calibration data, demonstrating the effectiveness of the proposed approach for environmental monitoring and soil assessment. This report is intended for environmental consultants, agricultural professionals, and research institutions involved in soil testing and analysis.
