Product Overview
Cesium 99.95% (trace metal basis) is an ultra-high-purity alkali metal designed for demanding laboratory applications where minimal trace impurities are critical. This grade ensures exceptional consistency in experimental results, making it ideal for advanced chemical synthesis, atomic spectroscopy, and specialized research requiring precise elemental control. The material is processed under stringent conditions to eliminate metallic contaminants, guaranteeing reliability in sensitive procedures. Its reactive nature necessitates careful handling under inert atmospheres or vacuum conditions to prevent oxidation. The 99.95% purity level meets rigorous analytical standards, providing researchers with a dependable reagent for experiments where trace metal interference could compromise data integrity. Packaged in sealed containers to maintain purity during storage and transport, this cesium variant offers long-term stability when stored under recommended conditions. Its uniform composition and documented trace analysis make it a preferred choice for laboratories prioritizing reproducibility in high-stakes research environments.
FAQs
1. What is the typical shelf life of cesium 99.95% when stored properly?
When stored under argon or in a vacuum-sealed container away from moisture and air, the material retains its specified purity for 24-36 months from the date of manufacture. Regular integrity checks of the container are recommended.
2. Can this cesium grade be used in vacuum deposition applications?
Yes, the 99.95% trace metal basis grade is suitable for vacuum deposition processes due to its low impurity profile, though specific chamber conditions and deposition parameters should be optimized for your target application.
3. What precautions are necessary when handling this high-purity cesium?
Always handle under dry argon or nitrogen atmosphere using appropriate PPE, including gloves and face shields. Cesium reacts violently with water and air, requiring specialized storage in mineral oil or sealed ampoules.
4. How does this compare to 99.9% cesium grades available in the market?
The 99.95% trace metal basis offers significantly lower levels of metallic contaminants (typically <50 ppm combined) compared to standard 99.9% grades, which may contain up to 100-200 ppm impurities affecting sensitive applications.
5. What documentation is provided with each shipment for quality verification?
Every batch includes a certificate of analysis detailing trace metal impurities via ICP-MS, assay confirmation, and handling instructions. Additional SDS and storage guidelines are provided upon request.
