Product Overview
This Puratronic™ calcium nitrate hydrate delivers exceptional 99.9995% purity on a metals basis, making it the ideal choice for applications where trace metal contamination must be absolutely minimized. The hydrated crystalline form ensures consistent solubility and reactivity in aqueous systems. Unlike standard reagent grades, this material undergoes rigorous purification processes to eliminate metallic impurities that could interfere with sensitive analytical techniques or advanced material synthesis. The tightly controlled manufacturing process guarantees batch-to-batch consistency, with comprehensive certificates of analysis provided for each lot. The product’s high assay specification is verified through ICP-MS analysis, confirming parts-per-billion level control of metallic contaminants. This level of purity is particularly critical in semiconductor manufacturing, where even minute impurities can affect device performance. The hydrate form provides stable moisture content, preventing variability in concentration that can occur with anhydrous materials. For researchers requiring the highest possible purity standards, this Puratronic™ grade represents the gold standard in calcium nitrate reagents.
FAQs
1. What is the difference between Puratronic™ and standard ACS grade calcium nitrate?
The Puratronic™ grade offers 99.9995% purity on a metals basis compared to typical ACS grade at 99% purity, with significantly lower trace metal impurities that are critical for advanced applications.
2. Can this product be used directly in semiconductor processing?
Yes, the ultra-low metallic impurity profile makes it suitable for semiconductor applications where trace metal contamination must be minimized.
3. What is the typical moisture content in this hydrated form?
The product contains 4 molecules of water per calcium nitrate molecule, providing consistent hydration without requiring additional moisture analysis.
4. How should this high-purity material be stored to maintain its specifications?
Store in the original container at room temperature, protected from moisture and direct sunlight to preserve the purity specifications.
5. What analytical methods are used to verify the 99.9995% purity?
The purity is confirmed through ICP-MS analysis for metallic impurities, with additional tests for anionic contaminants and water content.
