Multi-Element Analysis of Drinking Water Using the NexION 1000 ICP-MS Following ISO 17294-2 and (EU) 2020/2184
Elemental content is critical to the quality of drinking water. While mineral elements like calcium, magnesium, and iron are essential nutrients for the health of humans and animals, the adverse effects imposed by heavy metals like mercury, cadmium, arsenic, and lead usually at trace levels, cannot be neglected.

The international standard method ISO 17294 outlines the analysis of elements in water samples (for example, drinking water, surface water, groundwater, wastewater, and eluates) using ICP-MS. ISO 17294-1:20041 provides the general guidelines for using the ICP-MS technique, and ISO 17294-2:20162 describes the determination of selected elements, including uranium isotopes. In drinking water and relatively unpolluted waters, the limit of quantification (LOQ) lies between 0.002 μg/L and 1.0 μg/L for most elements (Table 1)
Also listed in this table are the LOQ specifications set by Directive (EU) 2020/2184. This directive aims to protect human health from the adverse effects of any contamination of water intended for human consumption by ensuring that it is wholesome and clean.
