Determination of Metals in Water by ICP-OES Test: EN ISO 11885 Compliant
The water industry is facing an increasingly stringent regulatory environment, with governments and international organizations setting ever-higher standards for water quality. One key area of focus is the determination of metals in water, which can have significant impacts on public health and environmental sustainability.
Real-World Applications in the Relevant Industry
In recent years, there has been a growing concern over the presence of metals such as lead, mercury, and arsenic in drinking water supplies. These contaminants can be hazardous to human health, particularly for vulnerable populations like children and pregnant women. For instance, exposure to lead in drinking water has been linked to developmental delays, reduced IQ, and even increased risk of cardiovascular disease.
To address these concerns, the European Standard EN ISO 11885 was developed as a method for determining metals in water by Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). This standard provides a reliable and reproducible approach to measuring metal concentrations in drinking water samples.
Clear Explanation of How the Testing is Performed
The ICP-OES technique involves bombarding a sample with high-energy argon ions, which ionize the metal atoms present. The resulting plasma then emits light at specific wavelengths corresponding to the energy levels of each metal. By detecting these emissions using an optical spectrometer, analysts can quantify the concentration of metals in the sample.
To perform an EN ISO 11885 compliant test, our laboratory follows a series of strict protocols:
1. Sample preparation: The water sample is filtered and acidified to prevent any interference or contamination during analysis.
2. ICP-OES calibration: The instrument is calibrated using a set of certified reference materials (CRMs) to ensure accurate measurements.
3. Sample measurement: The prepared sample is introduced into the ICP-OES system, where it is measured against a blank and CRMs to determine metal concentrations.
Risks and Legal Implications of Skipping the Service
Non-compliance with water quality regulations can result in serious consequences for businesses, including fines, reputational damage, and even cessation of operations. In Europe alone, there are several directives and standards that require regular monitoring of metals in drinking water supplies:
1. Directive 98/83/EC: Sets limits for certain heavy metals, including lead, mercury, and arsenic.
2. Water Framework Directive (WFD): Requires member states to achieve good chemical status for their surface waters by 2027.
Failure to meet these standards can result in costly penalties, as well as damage to a companys reputation and relationships with stakeholders.

FAQs
What types of metals can be determined using EN ISO 11885?
- The standard covers a wide range of metals, including lead, mercury, arsenic, and other heavy metals commonly found in water supplies.
Is the ICP-OES technique suitable for all types of water samples?
- Yes, the method is applicable to drinking water, wastewater, and surface water samples, as well as industrial effluent and groundwater.
How accurate are the results obtained using EN ISO 11885?
- The standard specifies a limit of detection (LOD) of 0.005 mg/L for most metals, with an expanded uncertainty of 10 for measurements above this level.
Can I send my samples to your laboratory directly?
- Yes, simply follow our sampling instructions and pack the samples securely to prevent damage during transit.
