Product Overview
Lanthanum(III) bromide, UltraDry™ grade with 99.9% rare earth oxide (REO) purity, is a high-performance anhydrous halide designed for applications demanding minimal moisture interference. The UltraDry™ designation ensures rigorous moisture control during packaging, making it ideal for air-sensitive reactions where even trace water content could compromise results. This crystalline solid maintains exceptional stability under inert conditions, with the high REO purity guaranteeing consistent stoichiometry in formulations. The compound’s hygroscopic nature necessitates careful handling, but the UltraDry™ packaging preserves its integrity until use. Its optical transparency in specific wavelength ranges also makes it valuable in specialized photonic applications. The 99.9% purity level minimizes metallic impurities that could act as catalysts or contaminants in sensitive processes. Unlike standard grades, this material undergoes additional purification steps to remove oxybromide formation risks, ensuring reliable performance in critical applications.
FAQs
1. What makes UltraDry™ lanthanum bromide different from standard grades?
The UltraDry™ designation indicates enhanced moisture control during production and packaging, with verified water content below 50 ppm compared to standard grades that may contain 100-500 ppm moisture.
2. Can this be used directly in glow discharge mass spectrometry?
While the high purity makes it suitable for many analytical techniques, the bromide ion may interfere with certain plasma-based methods unless properly matrix-matched with standards.
3. What’s the typical shelf life when stored unopened?
When kept in its original UltraDry™ packaging under inert atmosphere, the material maintains specifications for 24 months from the date of manufacture.
4. Are there any known incompatibilities with common laboratory materials?
The compound reacts violently with strong oxidizers and should not contact aluminum or magnesium powders, which can lead to exothermic reactions.
5. How does the 99.9% REO specification compare to 99.99% metal basis grades?
The REO specification accounts for all rare earth oxides as lanthanum oxide equivalents, while metal basis purity excludes oxygen content, making this grade more representative of actual usable lanthanum content.
