This Zinc (Zn) standard solution is part of the premium TraceCERT line, ensuring the highest level of reliability and traceability for analytical laboratories. The solution is prepared from high-purity zinc metal dissolved in a high-purity nitric acid matrix (approximately 2%). It is produced in an ISO 17034 and ISO/IEC 17025 accredited environment, guaranteeing a well-defined mass concentration with a calculated uncertainty. The standard is directly traceable to international standards (NIST), providing a robust foundation for quantitative elemental analysis in environmental monitoring, pharmaceutical testing, and metallurgy.
Advantages
- Highest Accuracy: Certified under the "double accreditation" of ISO 17034 and ISO/IEC 17025.
- Traceable to NIST: Every batch is directly traceable to a Standard Reference Material from the National Institute of Standards and Technology.
- High-Purity Matrix: Formulated with ultra-pure nitric acid and starting materials to prevent spectral interference from impurities.
- Detailed Documentation: Each bottle includes a comprehensive Certificate of Analysis (CoA) specifying the exact concentration, uncertainty, and expiration date.
- Long-term Stability: The 2% matrix prevents the formation of zinc hydroxides and ensures the analyte remains in stable ionic form.
