ISO 11885 ICP OES Metals Test in Water Validation Method Development Test
The ISO 11885 test method, utilizing Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), is a standardized approach for the accurate and precise determination of heavy metals in water. This service plays a critical role in ensuring compliance with international drinking water quality standards as defined by entities such as WHO, EPA, and EU regulations.
Our laboratory specializes in developing and validating analytical methods to meet specific client requirements or regulatory needs. This involves rigorous method validation studies that are essential for laboratories aiming to ensure their testing methods comply with global standards like ISO 17025 and ISO/IEC 17034.
The process of validating an ICP-OES method according to ISO 11885 begins with a thorough literature review followed by the establishment of appropriate quality control measures. We ensure that all testing conditions are optimized, including solution preparation, calibration standards, and instrument settings. This approach guarantees accurate detection limits and reproducibility.
Our team utilizes advanced ICP-OES instrumentation from reputable manufacturers such as PerkinElmer and Thermo Fisher Scientific. These instruments provide high sensitivity and selectivity, making them suitable for the low concentrations of heavy metals often found in water samples.
In addition to technical expertise, our laboratory adheres strictly to Good Laboratory Practices (GLP) which ensures reliability and traceability of results. We employ experienced scientists who have extensive knowledge in both theory and practical application of analytical chemistry.
The validation process typically includes several stages: method optimization, blank determination, calibration curve construction, linearity assessment, precision evaluation, accuracy verification, and robustness testing. Each stage is designed to ensure that the final validated method meets all specified requirements.
We also offer comprehensive consultation services tailored towards helping clients understand their specific analytical needs better. Our experts can assist with selecting appropriate sample matrices, optimizing extraction procedures, and interpreting complex datasets generated from ICP-OES analysis. Furthermore, we provide detailed reports that outline every step taken during the validation process along with all relevant data points.
By leveraging our robust infrastructure and cutting-edge technologies, we aim to deliver reliable results consistently across multiple locations worldwide. Whether you need assistance setting up a new analytical method or require validation services for existing methods, our team is committed to providing high-quality support throughout your project lifecycle.
