Product Overview
Calcium carbonate, Puratronic™ grade, delivers exceptional purity at 99.999% (metals basis), making it an indispensable reagent for laboratories demanding ultra-low trace metal contamination. This high-purity powder is meticulously processed to eliminate metallic impurities, ensuring reliable results in sensitive analytical procedures. The Puratronic™ designation guarantees consistency across batches, with rigorous quality control measures to maintain its ultra-high purity standards. Its fine, uniform particle size enhances solubility and reactivity, while the absence of detectable metallic contaminants prevents interference in spectroscopic, chromatographic, or gravimetric analyses. The product is packaged in airtight containers to preserve its purity during storage and handling. As a chemically stable compound, it maintains its integrity under standard laboratory conditions, though it remains sensitive to acidic environments. This grade is particularly valued in applications where even minute metallic impurities could compromise experimental accuracy or instrument calibration.
FAQs
1. What is the difference between Puratronic™ and standard reagent-grade calcium carbonate?
The Puratronic™ grade offers 99.999% purity on a metals basis, with trace metal impurities reduced to parts-per-billion levels, unlike standard reagent grades which typically contain higher metallic contaminants.
2. Can this product be used for preparing standard solutions in ICP-MS analysis?
Yes, its ultra-low metallic impurity profile makes it suitable for preparing calibration standards in ICP-MS and other trace metal analysis techniques where background contamination must be minimized.
3. How should this product be stored to maintain its purity?
Store in a cool, dry place in its original airtight container. Avoid exposure to acidic vapors or moisture, which could degrade the product or introduce contaminants.
4. Is this calcium carbonate compatible with organic solvents?
It is insoluble in most organic solvents but can be dispersed in polar solvents like water or alcohols. For specific solvent compatibility, pre-testing is recommended based on your application.
5. What alternatives exist if I need calcium carbonate with different purity levels?
For lower purity requirements, ACS reagent grade (99.0-99.5%) or technical grade (98%+) calcium carbonate are available, though they contain higher metallic and anionic impurities.
