Product Overview
This Premion® silver sulfate represents the pinnacle of chemical purity with 99.999% metals basis specification, making it ideal for applications demanding ultra-high precision. The compound presents as a white to off-white crystalline powder that remains stable under standard laboratory conditions. Its non-hygroscopic nature ensures consistent performance without moisture absorption concerns. The material demonstrates excellent solubility in water (834 g/L at 20°C) while remaining insoluble in ethanol, enabling selective dissolution protocols. The silver content of 69.0% by mass provides predictable stoichiometry for quantitative reactions. Each batch undergoes rigorous ICP-MS analysis to verify trace metal impurities remain below 10 ppm, with individual contaminants like lead, iron, and copper typically measuring under 1 ppm. The crystalline structure maintains uniformity across all particle sizes (typically 50-150 μm), ensuring reproducible results in gravimetric analyses. When stored in tightly sealed containers away from light, the product maintains its specified purity for at least 24 months from the date of manufacture.
FAQs
1. What is the actual silver content percentage in this product?
The product contains 69.0% silver by mass, with the remaining 31.0% being sulfate groups, calculated from the molecular formula Ag₂SO₄.
2. How does this compare to standard ACS-grade silver sulfate?
This Premion® grade offers significantly higher purity (99.999% vs 99.0-99.5% for ACS) with stricter controls on trace metal impurities, particularly for heavy metals which are maintained below 1 ppm.
3. What type of container is recommended for long-term storage?
Use amber glass bottles with PTFE-lined caps to prevent photodegradation and moisture ingress. Avoid plastic containers as silver ions may leach into certain polymers.
4. Can this be used for preparing silver nanoparticle synthesis?
Yes, the ultra-low impurity profile makes it suitable as a silver ion source for nanoparticle synthesis, though additional purification steps may be required depending on the specific nanoparticle protocol.
5. What’s the typical lead time for this product in India?
Standard pack sizes (5g, 25g) typically ship within 3-5 business days from our Indian distribution centers, while 100g quantities may require 7-10 days for special packaging.
