Product Overview
This Bismuth 10 ppm ICP-ML single-element standard represents the gold standard for trace metal analysis in advanced spectroscopic techniques. Formulated in a 1-5% high-purity nitric acid matrix, the solution eliminates matrix interferences while maintaining exceptional stability over extended storage periods. The concentration is certified at 10 ± 0.5 ppm with NIST-traceable reference materials, ensuring compliance with ISO 17034 and GLP standards. Each batch undergoes rigorous multi-point quality control including ICP-MS verification against primary standards, with certificates of analysis documenting the complete elemental purity profile. The ultra-low background matrix (total impurities < 10 ppb) makes it particularly suitable for ultra-trace analysis where background contamination must be minimized. Packaged in Class A borosilicate glass bottles with PTFE-lined caps to prevent leaching or adsorption, the standard maintains its certified concentration for 24 months when stored at 15-25°C. The solution's homogeneous composition ensures immediate readiness for use without requiring additional preparation steps, while the amber glass packaging protects against photodegradation of sensitive components.
FAQs
1. What is the exact nitric acid concentration in this Bismuth standard?
The standard uses a 1-5% ultra-pure nitric acid matrix, optimized to balance analyte stability while minimizing spectral interferences during ICP analysis. The exact concentration is specified in the certificate of analysis for each batch.
2. Can this standard be used for both ICP-OES and ICP-MS applications?
Yes, the 10 ppm concentration and ultra-pure matrix make it suitable for both techniques, though you may need to dilute for ICP-MS applications where lower detection limits are required.
3. What materials are used for the bottle and cap to prevent contamination?
The solution comes in Class A borosilicate glass bottles with PTFE-lined polypropylene caps, specifically chosen to resist chemical attack and prevent elemental leaching that could affect your analysis.
4. How does the shelf life compare to other ICP standards on the market?
With proper storage at 15-25°C, this standard maintains its certified concentration for 24 months, which is 20-30% longer than many competitive products due to our proprietary stabilization process.
5. What documentation is provided with each bottle for quality assurance?
Each bottle includes a comprehensive certificate of analysis documenting the certified concentration, uncertainty values, expiration date, batch number, and complete ICP-MS verification data against NIST-traceable reference materials.
