Product Overview
This ultra-high-purity ammonium sulfate (99.9995% trace metal basis) represents the gold standard for applications demanding exceptional purity and minimal trace metal contamination. Engineered through advanced purification processes, this crystalline powder maintains consistent particle size distribution and exceptional solubility in water, ensuring reliable performance in critical laboratory procedures. The trace metal basis specification guarantees that residual metallic impurities are reduced to parts-per-billion levels, making it particularly suitable for sensitive analytical techniques where even minute contaminations could compromise results. The product’s stability under standard laboratory conditions and its compatibility with most common lab solvents further enhance its versatility. Each batch undergoes rigorous quality control testing to verify the stated purity level, with certificates of analysis available upon request. The material’s low hygroscopicity ensures consistent weight measurements and prolonged shelf life when stored properly. This grade of ammonium sulfate serves as an essential reagent in laboratories where precision and reproducibility are paramount, offering researchers confidence in their experimental outcomes.
FAQs
1.What is the significance of the “trace metal basis” specification in this ammonium sulfate?
This specification indicates that the product has been specially purified to minimize trace metal contaminants, with metallic impurities reduced to extremely low concentrations (typically parts-per-billion range), making it suitable for applications where metal ions could interfere with results or analyses. 2
2.How should this high-purity ammonium sulfate be stored to maintain its quality?
Store the product in its original, tightly sealed container at room temperature, away from direct sunlight and moisture. Keep it separated from strong acids, bases, and oxidizing agents to prevent potential reactions that could compromise purity. 3
3.Is this grade of ammonium sulfate compatible with standard laboratory glassware?
Yes, this product is fully compatible with borosilicate glass and most common laboratory plastics. However, for applications requiring the absolute lowest metal contamination, consider using metal-free containers or glassware that has been acid-washed. 4
4.What documentation is provided with this product to verify its purity?
Each batch comes with a certificate of analysis that details the actual purity level, trace metal content, and other relevant quality parameters. This documentation is available upon request from the supplier. 5
5.Are there any special handling precautions for this ultra-pure ammonium sulfate?
While not hazardous under normal laboratory conditions, it’s recommended to use standard laboratory practices including wearing gloves and safety glasses when handling. Avoid creating dust clouds and work in a well-ventilated area to prevent potential respiratory irritation from fine particles.
