Product Overview
Cadmium sulfate hydrate in Puratronic™ grade offers exceptional purity at 99.996% (metals basis), making it a critical reagent for applications demanding minimal trace metal contamination. This crystalline powder is synthesized under stringent conditions to ensure consistent composition and reliability in sensitive analytical procedures. The hydrate form provides enhanced solubility in aqueous solutions while maintaining stability during storage. Its high purity eliminates interference in spectroscopic, electrochemical, and gravimetric analyses, where even trace impurities can skew results. The compound’s precise stoichiometry and low moisture content make it suitable for preparing standard solutions, calibration curves, and as a precursor in specialized syntheses. Unlike technical-grade alternatives, Puratronic™ cadmium sulfate undergoes rigorous multi-stage purification to remove metallic and anionic contaminants, ensuring reproducibility in high-precision workflows. The product is packaged in airtight containers to prevent hydration changes and oxidation, preserving its integrity until use.
FAQs
1. What is the difference between Puratronic™ and reagent-grade cadmium sulfate hydrate?
Puratronic™ grade undergoes additional purification steps to achieve 99.996% metals basis purity, whereas reagent-grade typically ranges between 98-99%. This reduces trace metal contaminants that could interfere with sensitive analyses like ICP-MS or polarography.
2. Can this product be used for preparing primary standards in titrimetry?
Yes, the high purity and well-defined stoichiometry of this cadmium sulfate hydrate make it suitable for preparing primary standards, provided the hydrate content is accounted for in calculations.
3. How should this compound be stored to maintain its purity?
Store in a tightly sealed container under dry, inert conditions (e.g., desiccator or nitrogen-purged cabinet) at room temperature. Avoid exposure to air or moisture to prevent hydration changes or oxidation.
4. Is this compatible with standard lab glassware, or are special materials required?
The compound is compatible with borosilicate glass and PTFE labware. Avoid prolonged contact with metals or rubber stoppers, as trace leaching or degradation may occur over time.
5. What alternatives exist if Puratronic™ grade is unavailable?
For less critical applications, ACS reagent-grade cadmium sulfate (99%+) can be used, though it may introduce higher background interference. For ultra-trace work, consider cadmium metal standards in acidic solutions as alternatives.
