Product Overview
This ultra-pure 99.999% potassium bromide (KBr) is specifically manufactured for applications requiring minimal trace metal contamination. The crystalline powder form ensures consistent performance in spectroscopy, particularly FTIR, where optical clarity is critical. The high purity grade eliminates interference from metallic impurities, making it ideal for sensitive analytical techniques. Its low hygroscopicity compared to other alkali halides enhances stability during storage and handling. The material undergoes rigorous purification processes to meet trace metal basis specifications, ensuring reproducibility in research and industrial applications. The absence of detectable impurities guarantees reliable baseline readings in spectroscopic analysis. This grade is particularly suited for preparing KBr pellets or windows where even minor contaminants could compromise results. The product’s uniformity and particle size distribution are optimized for efficient pressing into transparent discs without requiring additional binders.
FAQs
1. What is the difference between 99.999% and standard potassium bromide?
The 99.999% grade has undergone additional purification steps to remove trace metal contaminants that could interfere with sensitive analytical techniques. Standard grades typically contain higher levels of impurities that may affect spectroscopic readings.
2. Can this potassium bromide be used for preparing IR spectroscopy samples?
Yes, this ultra-pure grade is specifically designed for IR spectroscopy applications where optical transparency and minimal interference are required. Its low moisture content and high purity make it ideal for preparing KBr pellets.
3. What is the typical shelf life of this product when stored properly?
When stored in a cool, dry environment in its original sealed container, this potassium bromide maintains its specified purity for at least 24 months from the date of manufacture.
4. Are there any special handling requirements for this high-purity grade?
While not hazardous, this product should be handled in a clean environment to prevent contamination. Use non-metallic tools when transferring the powder to avoid introducing metal impurities.
5. How does the particle size affect its use in spectroscopy?
The controlled particle size distribution ensures optimal compaction when preparing KBr pellets, resulting in clear, bubble-free discs that provide consistent transmission in the infrared region.
