ISO 17294-2 Water Quality - ICP-MS Determination of Metals

Comprehensive Guide to ISO 17294-2 Water Quality - ICP-MS Determination of Metals Laboratory Testing Service Provided by Eurolab

ISO 17294-2, Water quality - Inductively coupled plasma mass spectrometry (ICP-MS) - Part 2: Determination of metals, is a standard that specifies the requirements for the determination of metals in water by inductively coupled plasma mass spectrometry (ICP-MS). This standard is part of the ISO 17294 series, which covers the determination of various elements in water using ICP-MS.

The legal and regulatory framework surrounding this testing service is governed by various international and national standards. In Europe, for example, the European Unions Drinking Water Directive (98/83/EC) sets limits for the concentration of certain substances in drinking water. Similarly, the US Environmental Protection Agency (EPA) has established Maximum Contaminant Levels (MCLs) for various substances in drinking water under the Safe Drinking Water Act.

The international standards that apply to this specific laboratory test include:

The standard development organizations that govern this testing service include the International Organization for Standardization (ISO), the American Society for Testing and Materials (ASTM), and the European Committee for Standardization (CEN).

Standards evolve and get updated to reflect new technologies, methodologies, and regulatory requirements. For example, ISO 17294-2 was revised in 2016 to include additional metals and improved method validation procedures.

The standard numbers and their scope are as follows:

Compliance with these standards is mandatory for industries that require accurate and reliable metal analysis in water. Non-compliance can result in product recalls, financial losses, and reputational damage.

The specific test described by ISO 17294-2 is needed and required because it provides a fast, accurate, and reliable method for determining metals in water. This is particularly important in industries such as:

The business and technical reasons for conducting this test include:

The consequences of not performing this test can be severe, including:

The ICP-MS method used in ISO 17294-2 involves the following steps:

1. Sample preparation: The water sample is prepared for analysis by adjusting its pH, diluting it with a suitable matrix, and adding internal standards.

2. Instrument setup: The ICP-MS instrument is set up according to the manufacturers instructions, including optimization of plasma and ion source conditions.

3. Measurement: The prepared sample is introduced into the ICP-MS instrument, where it is atomized and ionized.

4. Data analysis: The resulting mass spectrum is analyzed using specialized software to identify and quantify the metals present in the sample.

The testing equipment and instruments used include:

The testing environment requirements are as follows:

Sample preparation procedures involve adjusting the pH and diluting the sample with a suitable matrix.

Testing parameters and conditions include:

Conclusion

In conclusion, ISO 17294-2 is an essential standard that specifies the requirements for determining metals in water using ICP-MS. Compliance with this standard is mandatory for industries that require accurate and reliable metal analysis in water. Non-compliance can result in product recalls, financial losses, and reputational damage.
