Product Overview
Nitric acid, 67% NORMATOM® Ultrapure is a high-purity reagent designed for demanding laboratory applications where trace impurities can compromise results. This ultrapure grade nitric acid undergoes rigorous purification processes to ensure ultra-low levels of metallic and non-metallic contaminants, making it ideal for sensitive analytical techniques. The 67% concentration provides optimal reactivity for sample digestion, particularly in ICP-MS, AAS, and other trace metal analysis protocols. Its consistent composition minimizes background interference, enhancing detection limits and reproducibility in quantitative analyses. The acid is stabilized to prevent degradation during storage while maintaining its oxidative properties. Packaged in high-density polyethylene containers to prevent contamination, this reagent meets the stringent requirements of modern research laboratories. Its versatility extends to various synthesis applications where high-purity reagents are essential for achieving reliable outcomes.
FAQs
1. What is the typical shelf life of this ultrapure nitric acid?
The shelf life is approximately 24 months from the date of manufacture when stored unopened in its original container at room temperature, protected from light and moisture.
2. Is this nitric acid suitable for digesting organic samples?
Yes, the 67% concentration and ultrapure grade make it highly effective for digesting organic matrices while minimizing contamination from the reagent itself.
3. What precautions should be taken when handling this acid?
Always use in a well-ventilated fume hood with appropriate PPE including acid-resistant gloves, goggles, and lab coat due to its corrosive and oxidizing properties.
4. How does this compare to standard reagent-grade nitric acid?
This ultrapure grade contains significantly lower levels of metallic impurities (typically <10 ppt for most elements) compared to standard reagent grades which may contain ppm levels of contaminants.
5. Can this be used for cleaning glassware for trace analysis?
Yes, its high purity makes it excellent for cleaning glassware and equipment used in trace metal analysis, though a final rinse with ultrapure water is recommended.
