ISO 11885 ICP OES Trace Metals Residual Test in Water
The ISO 11885 standard provides a robust framework for determining trace metal concentrations in water using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). This method is particularly useful for quality managers, compliance officers, and R&D engineers who need accurate and precise measurement of trace metals in water. The test ensures that water meets stringent environmental regulations and safety standards.
The ISO 11885 standard specifies the use of ICP-OES for measuring a wide range of trace elements such as copper, lead, zinc, nickel, cadmium, chromium, and many others. These metals can have significant impacts on public health and water quality if present in high concentrations. The test ensures that the residual levels are within acceptable limits set by regulatory bodies like the World Health Organization (WHO) and other international standards.
Our laboratory follows a strict procedure to ensure accurate results. Specimen preparation involves dilution of water samples to appropriate concentrations, ensuring no physical contamination, and then transferring them into ICP-OES compatible containers. The instrument is calibrated according to ISO 17025 requirements before each test run. Once the calibration is verified, the sample solution is injected into the plasma source.
The ICP-OES measures elemental emission spectra from excited ions in a high-temperature argon plasma. This method provides excellent sensitivity and accuracy, making it suitable for detecting trace metal concentrations as low as parts per billion (ppb). After acquisition of data points, they are compared against calibration standards to determine the exact concentration of each element present.
The results generated by this process are highly reliable due to stringent quality control measures implemented throughout our testing procedure. Our laboratories adhere strictly to ISO 17025 guidelines which ensure that all tests conducted meet high levels of accuracy and precision.
Our team of experienced chemists and technicians use state-of-the-art equipment to perform these tests efficiently. This includes advanced ICP-OES systems capable of handling a variety of sample types including drinking water, industrial wastewater, stormwater runoff, and more.
The ISO 11885 standard plays an important role in ensuring that any trace metal present does not exceed safe thresholds established by relevant authorities. By adhering to this standard, we provide peace-of-mind knowing that our clients receive accurate results every time.
Our commitment extends beyond just performing the test; it also includes providing comprehensive reports detailing all findings along with recommendations for corrective actions if necessary. These reports are formatted according to international standards ensuring they can be easily understood by decision-makers across various industries.
