Product Overview
This selenium standard solution is a high-purity, 1 g/L single-element reference material specifically formulated for atomic absorption spectroscopy (AAS) applications. The solution is prepared using ultra-pure selenium compounds dissolved in a stabilized matrix to prevent precipitation and ensure long-term stability. The analytical-grade formulation guarantees minimal interference from contaminants, making it ideal for precise calibration and trace-level selenium analysis. Each batch undergoes rigorous quality control to verify concentration accuracy and homogeneity, ensuring consistent performance across multiple analyses. The solution is packaged in a high-density polyethylene (HDPE) bottle to maintain integrity during storage and handling. Its stable shelf life and ready-to-use format eliminate the need for complex preparation, saving valuable lab time. The product adheres to international standards for AAS reference materials, providing reliable results for both routine and research-grade applications.
FAQs
1. What is the shelf life of this selenium standard solution?
The solution remains stable for 24 months from the date of manufacture when stored unopened at room temperature, away from direct sunlight and moisture.
2. Can this solution be used for ICP-OES or ICP-MS analysis?
While primarily designed for AAS, it can be used for ICP-OES with appropriate dilution, but matrix effects should be evaluated for ICP-MS applications.
3. What is the recommended storage temperature for this standard?
Store between 15°C to 25°C in its original container with the cap tightly sealed to prevent contamination or evaporation.
4. Does this solution contain any preservatives or stabilizers?
Yes, it includes trace amounts of nitric acid as a stabilizer to maintain selenium solubility and prevent microbial growth.
5. How should I dispose of unused selenium standard solution?
Follow local regulations for hazardous chemical disposal; neutralize with appropriate reagents before disposal if required by your institution’s safety protocols.
