UNE EN ISO 11885 Spectroscopic ICP OES Testing of Waters
The UNE EN ISO 11885 standard specifies a method for the determination of trace elements in water by means of Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). This service is particularly important for industries dealing with environmental, pharmaceutical, and industrial waste sectors where compliance with stringent chemical analysis standards is crucial. The primary purpose of this testing is to ensure that the concentrations of trace elements in water samples meet regulatory and quality control thresholds.
The process begins with the collection and preparation of water samples according to specified guidelines. Sample preparation involves filtration, digestion if necessary, and dilution to appropriate concentrations for analysis. Once prepared, these samples are introduced into the ICP-OES instrument where they undergo a multi-step analytical procedure:
- Atomization in an inductively coupled plasma (ICP) creates free atoms or ions.
- Excitation of these atoms or ions by microwave energy causes them to emit characteristic light emissions.
- The emitted light is then analyzed to determine the concentration of various trace elements present in the sample.
This method allows for precise and accurate quantification of numerous metals like copper, zinc, lead, cadmium, and other essential or toxic elements. The reliability and accuracy provided by this technique make it an indispensable tool in industries dealing with water quality assurance.
The UNE EN ISO 11885 standard ensures that the results are consistent across different laboratories, which is crucial for regulatory compliance and inter-laboratory comparisons. This service not only helps companies meet environmental regulations but also enhances trust among stakeholders by providing transparent, reproducible data.
Compliance with this standard can significantly impact a company’s reputation and operational efficiency. For instance, industries facing stringent water quality standards, such as pharmaceuticals and electronics manufacturing, rely heavily on accurate spectroscopic analysis to ensure their products meet safety and efficacy requirements.
The benefits of adhering to UNE EN ISO 11885 extend beyond mere compliance; it also aids in identifying potential issues early, thereby preventing costly disruptions. By maintaining consistent water quality standards through regular testing, companies can preemptively address any deviations from expected levels, ensuring ongoing operational stability and product reliability.

| Zinc | 0.02 | 1 - 100,000 |
| Cadmium | 0.001 | 0.5 - 50,000 |
| Lead | 0.002 | 1 - 100,000 |
The precision and accuracy of the UNE EN ISO 11885 method are critical for ensuring reliable results. The table above illustrates the detection limits and sensitivity ranges for key elements analyzed by this service. These parameters underscore the comprehensive nature of our testing capabilities, allowing us to detect even minute concentrations of harmful substances.
In conclusion, adhering to UNE EN ISO 11885 ensures that water samples are analyzed with utmost precision and reliability, providing clients with confidence in their data and compliance status. This service is an essential tool for maintaining high standards in industries where water quality plays a pivotal role.
Scope and Methodology
The scope of the UNE EN ISO 11885:2016 standard encompasses the determination of trace elements in water samples using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). This method is particularly useful for detecting and quantifying various metallic species, including but not limited to copper, zinc, lead, and cadmium. The methodology involves several critical steps:
- Sample Collection: Proper collection of water samples ensures that the analysis accurately reflects the composition of the sample.
- Preparation: Samples are prepared according to standardized procedures to ensure homogeneity and stability. This may involve filtration, digestion using acids like nitric acid, or dilution.
- Instrumentation Setup: The ICP-OES instrument is calibrated and configured for optimal performance before analysis.
- Analysis: Samples are introduced into the plasma source where they undergo excitation. Emitted light is captured, recorded, and analyzed to determine concentrations of target elements.
- Data Interpretation: Raw data from the instrument is processed using software that correlates emitted wavelengths with known element-specific signatures.
- Reporting: Results are compiled into a comprehensive report detailing all detected elements, their concentrations, and any relevant compliance information.
The methodology outlined in UNE EN ISO 11885 ensures consistency and accuracy across different laboratories. This standardization is crucial for industries that rely on precise water quality data to meet regulatory requirements and ensure product safety.
