Product Overview
The Specpure® cobalt plasma standard solution (10µg/ml) is a high-precision reference material designed for demanding analytical applications where accuracy and traceability are critical. Formulated using ultra-pure cobalt in a stabilized aqueous matrix, this solution minimizes matrix interferences, ensuring reliable calibration and quantification in spectroscopic techniques such as ICP-OES, ICP-MS, and atomic absorption spectroscopy (AAS). The Specpure® grade guarantees low impurity levels, with contaminants controlled to sub-ppb levels, making it suitable for ultra-trace analysis in environmental, clinical, and industrial laboratories. Each batch undergoes rigorous quality control, including multi-element analysis, to confirm concentration accuracy and homogeneity. The solution is supplied in a high-density polyethylene (HDPE) bottle to prevent leaching or contamination, with a tamper-evident seal for integrity assurance. Compatible with most autodilution systems, it eliminates the need for manual dilution in routine workflows. The 10µg/ml concentration provides an optimal balance between sensitivity and linear dynamic range, reducing the risk of overloading detectors while maintaining signal stability. For long-term storage, the solution remains stable for up to 24 months when kept at 15–25°C, protected from light and moisture. Its lot-specific certificate of analysis includes detailed uncertainty statements, traceability to NIST SRMs, and method validation data, supporting compliance with ISO/IEC 17025 and GLP standards.
FAQs
1. What is the shelf life of this cobalt plasma standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at 15–25°C, away from direct sunlight and moisture. Once opened, use within 6 months for optimal accuracy.
2. Can this standard be used for both ICP-OES and ICP-MS?
Yes, the Specpure® cobalt plasma standard is compatible with both ICP-OES and ICP-MS, as well as AAS. Its ultra-low impurity profile ensures minimal spectral interferences, even in high-sensitivity ICP-MS applications.
3. Is this solution traceable to national or international standards?
Each batch is traceable to NIST Standard Reference Materials (SRMs) and is accompanied by a certificate of analysis with uncertainty data, ensuring metrological reliability for accredited laboratories.
4. What material is the bottle made of, and is it acid-resistant?
The solution is packaged in a high-density polyethylene (HDPE) bottle, which is resistant to dilute acids and bases. However, avoid prolonged exposure to concentrated acids or organic solvents to prevent degradation.
5. Are there lower or higher concentration alternatives available?
Alternative concentrations (e.g., 1µg/ml, 100µg/ml) may be available upon request. Contact customer support for custom dilution options or bulk packaging requirements.
