This Lead (Pb) standard solution belongs to the premium TraceCERT product line, representing the highest tier of traceability and precision. The solution is prepared from high-purity lead metal dissolved in a high-purity nitric acid matrix (typically 2%). It is manufactured in an environment accredited to both ISO 17034 and ISO/IEC 17025. This ensures a precisely defined mass concentration with a rigorously calculated uncertainty. The standard is directly traceable to the National Institute of Standards and Technology (NIST), making it an essential tool for quantitative analysis in environmental monitoring, forensic toxicology, and industrial quality control.
Advantages
- Highest Regulatory Compliance: Produced under the "double accreditation" of ISO 17034 and ISO/IEC 17025 for maximum reliability.
- Traceability to NIST: Every batch is directly traceable to a Standard Reference Material (SRM) from NIST.
- Ultra-High Purity: Formulated using high-purity starting materials and ultra-pure nitric acid to minimize spectral or chemical interference.
- Extensive Documentation: Each bottle is accompanied by a comprehensive Certificate of Analysis (CoA) providing the exact concentration, uncertainty, and expiration date.
- Stable Matrix: The 2% nitric acid matrix ensures the lead ions remain stable in solution, preventing precipitation or adsorption to container walls.
