Product Overview
This Puratronic™ calcium carbonate delivers 99.99% purity on a metals basis, ensuring minimal trace element interference for critical laboratory applications. The ultra-high purity grade makes it particularly suitable for analytical chemistry, where even minute impurities can compromise results. The fine, free-flowing powder form allows for precise weighing and homogeneous mixing in solutions or solid-state reactions. Unlike standard reagent grades, this material undergoes rigorous purification to eliminate metallic contaminants, providing consistent performance in sensitive assays, titrations, and synthesis protocols. The stability of calcium carbonate under normal conditions ensures long shelf life without degradation, while its well-characterized composition allows for reliable use in quantitative analyses. Whether used as a primary standard, buffer component, or reaction substrate, this grade offers the purity required for advanced research and quality control applications.
FAQs
1. What is the difference between Puratronic™ and standard reagent grade calcium carbonate?
The Puratronic™ grade is refined to 99.99% purity with significantly lower metal impurities compared to standard reagent grades, which typically contain higher levels of trace elements.
2. Can this calcium carbonate be used for preparing standard solutions?
Yes, the high purity and well-defined composition make it suitable for preparing primary standard solutions in titrimetric analysis.
3. How should this product be stored to maintain its purity?
Store in a tightly sealed container in a cool, dry place away from moisture and acidic vapors to prevent contamination or decomposition.
4. Is this calcium carbonate compatible with strong acids?
It will react with strong acids to produce carbon dioxide, water, and the corresponding calcium salt, which is a standard chemical behavior.
5. What certification or analysis is provided with this product?
The product includes a certificate of analysis detailing the purity, trace metal content, and other relevant specifications.
