Product Overview
Ammonium sulfate Puratronic™ is an ultra-high purity reagent with 99.999% (metals basis) certification, designed for applications requiring minimal trace metal contamination. This crystalline powder undergoes rigorous purification processes to eliminate metallic impurities, making it ideal for demanding laboratory environments. The Puratronic™ grade ensures consistent performance in analytical chemistry, semiconductor manufacturing, and other high-precision synthesis where metal ion interference must be minimized. Its stable chemical properties and low hygroscopicity allow for reliable long-term storage without degradation. The product is packaged in airtight containers to prevent moisture absorption and contamination, maintaining its purity until use. This grade exceeds standard ACS specifications, providing researchers with confidence in their experimental reproducibility. The absence of detectable metal contaminants makes it particularly valuable for ICP-MS, AA spectroscopy, and other trace analysis techniques where background interference could compromise results.
FAQs
1. What is the difference between Puratronic™ and ACS grade ammonium sulfate?
Puratronic™ grade offers 99.999% purity on a metals basis, specifically engineered to eliminate trace metal contaminants that are present in standard ACS grade (typically 99% pure). This makes it superior for applications sensitive to metal ion interference.
2. Can this product be used for protein precipitation?
While ammonium sulfate is commonly used for protein precipitation, this Puratronic™ grade is overqualified for such applications. Its ultra-high purity is better suited for trace analysis where metal contamination must be avoided.
3. How should this be stored to maintain its purity?
Store in the original airtight container at room temperature, away from direct sunlight and moisture. Avoid transferring to other containers unless they are certified metal-free to prevent contamination.
4. Is this product compatible with HPLC or GC analysis?
Yes, its ultra-low metal content makes it suitable as a mobile phase additive or buffer component in HPLC and GC applications where metal interference could affect column performance or detector sensitivity.
5. What alternatives exist for less critical applications?
For general laboratory use, ACS grade (99% purity) or reagent grade ammonium sulfate would be more cost-effective alternatives, though they contain higher levels of trace metals.
