Product Overview
Calcium carbonate, Puratronic grade, offers exceptional purity at 99.99% (metals basis), making it ideal for demanding laboratory applications where trace metal contamination must be minimized. This high-purity form is processed under stringent conditions to ensure consistent composition, low impurity levels, and reliable performance in critical experiments. The fine, free-flowing powder dissolves uniformly, providing accurate results in analytical procedures. Its high assay guarantees minimal interference from metallic impurities, which is essential for sensitive techniques like spectroscopy, chromatography, and gravimetric analysis. The Puratronic grade is specifically designed for applications requiring ultra-low trace metal content, ensuring reproducibility in research and development workflows. Packaged in airtight containers to prevent moisture absorption and contamination, this product maintains its integrity during storage and handling. Whether used as a reagent, standard, or buffer component, this calcium carbonate delivers precision and reliability for advanced laboratory requirements.
FAQs
1. What is the difference between Puratronic and standard calcium carbonate?
Puratronic calcium carbonate undergoes additional purification steps to achieve 99.99% purity (metals basis), reducing trace metal impurities that can interfere with sensitive analyses. Standard grades typically have higher impurity levels.
2. Can this product be used for preparing standard solutions?
Yes, its high purity and consistent composition make it suitable for preparing standard solutions where accurate concentration and minimal contamination are critical.
3. How should this calcium carbonate be stored to maintain purity?
Store in a cool, dry place in its original airtight container. Avoid exposure to moisture or direct sunlight, as humidity can cause clumping or degradation over time.
4. Is this product compatible with acidic solutions?
Calcium carbonate reacts with acids to release carbon dioxide. If used in acidic environments, ensure proper ventilation and handle with care to avoid rapid gas evolution.
5. What alternatives exist for applications requiring lower purity?
For less demanding applications, reagent-grade or technical-grade calcium carbonate (typically 98-99% purity) can be used, though they may contain higher trace metal impurities.
