This Iron (Fe) standard solution is part of the TraceCERT® product line, which represents the highest level of accuracy and traceability. The solution is prepared from high-purity iron metal dissolved in a high-purity nitric acid matrix (typically 2%). Each bottle is produced in an ISO/IEC 17025 and ISO 17034 accredited environment, ensuring the lowest possible uncertainty. It is used as a reference material to determine iron concentrations in environmental, clinical, and industrial samples, providing a reliable link to international standards (NIST).
Advantages
- Certified Accuracy: Produced under ISO 17034 and ISO/IEC 17025 accreditation for maximum reliability.
- NIST Traceability: Directly traceable to the National Institute of Standards and Technology (NIST) Standard Reference Materials.
- High Purity: Prepared using high-purity starting materials and acids to minimize background interference.
- Comprehensive Documentation: Supplied with a detailed Certificate of Analysis (CoA) containing exact concentration, uncertainty, and expiration date.
- Excellent Stability: Optimized acid matrix ensures the iron ions remain in solution without precipitation for the duration of its shelf life.
