EN ISO 11885 Multi-Element Analysis by ICP-OES
The EN ISO 11885 standard specifies a method of multi-element analysis in drinking water using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). This service is critical for ensuring that the drinking water supplied meets stringent international quality and safety standards. The primary focus is on detecting and quantifying trace elements, which can have significant implications for human health.
The process involves several key steps, starting with the collection of a water sample. Proper sampling is crucial to ensure accurate results. Samples are then prepared according to the ISO 11885 protocol, which includes filtering and diluting the water as necessary. The prepared samples are introduced into the ICP-OES instrument, where they are atomized, excited, and detected by optical emission.
The ICP-OES method is particularly effective for multi-element analysis due to its high sensitivity and low detection limits. This makes it ideal for detecting trace elements that may be present in very small concentrations. The method can analyze up to 70 different elements simultaneously, which is a significant advantage when assessing the quality of drinking water.
The results are reported according to EN ISO standards, ensuring consistency and comparability across laboratories. The report typically includes detailed data on the concentration of each detected element, along with any relevant limits set by regulatory bodies such as WHO or EPA. It also provides recommendations for further action if any elements exceed acceptable levels.
One of the key advantages of using EN ISO 11885 is its ability to handle a wide range of water samples, from surface and ground waters to treated drinking water. This versatility makes it an essential tool in both routine monitoring and investigative scenarios. The method also benefits from rapid analysis times and minimal sample preparation steps, which are particularly valuable for time-sensitive applications.
The service is typically used by quality managers, compliance officers, R&D engineers, and procurement professionals who need to ensure that their water supply meets or exceeds international standards. By providing accurate and reliable multi-element analysis, this service plays a crucial role in maintaining public health and environmental safety.
Some of the trace elements commonly analyzed include arsenic, lead, cadmium, chromium, copper, iron, manganese, nickel, zinc, and selenium. These elements are of particular concern due to their potential toxic effects on human health when present at high concentrations. The EN ISO 11885 method allows for precise quantification of these elements, enabling effective risk management strategies.
In addition to routine monitoring, the service is also used in investigative scenarios where there may be concerns about contamination or unusual water quality conditions. By providing comprehensive and accurate data on multiple elements simultaneously, EN ISO 11885 helps identify potential sources of contamination and assess their impact on water quality.
| Element | Common Uses | Regulatory Limits (µg/L) |
|---|---|---|
| Arsenic | Toxicity, Risk Management | <10 µg/L |
| Cadmium | Toxicity, Risk Management | <3 µg/L |
| Lead | Toxicity, Risk Management | <15 µg/L |
| Copper | Metallic Taste, Health Effects | <2.0 mg/L |
| Zinc | Corrosion Control, Health Effects | <1.0 mg/L |
The service is not only valuable for regulatory compliance but also for internal quality control and assurance programs. By providing accurate and reliable data on multiple elements simultaneously, it helps organizations maintain the highest standards of water quality.
In conclusion, EN ISO 11885 Multi-Element Analysis by ICP-OES is a critical tool for ensuring the safety and quality of drinking water. Its ability to detect and quantify trace elements with high precision makes it an essential service for quality managers, compliance officers, R&D engineers, and procurement professionals.
