This application report presents a validated method for the analysis of 28 trace and major elements in drinking water using inductively coupled plasma mass spectrometry (ICP-MS), in full compliance with ISO 17294-2. The method enables accurate quantification of toxic elements such as arsenic, cadmium, lead, and mercury, as well as essential macro-elements like calcium and magnesium. Calibration standards, certified reference materials, and quality control samples were used to ensure accuracy, with all limits of quantification well below ISO thresholds and correlation coefficients exceeding 0.9995.
The method, using the SPECTROGREEN MS, demonstrates excellent long-term stability, maintaining consistent recoveries across a 10-hour analytical sequence without recalibration. Matrix interferences are effectively addressed using helium collision mode, ensuring reliable results across diverse sample types. Designed for routine use in environmental and regulatory laboratories, this ICP mass spectrometry approach supports efficient, high-throughput monitoring of drinking water quality, providing the precision and robustness required for public health and compliance assurance.
