FAQs
1. What distinguishes PuratrOnic™ grade from standard mercury(II) sulfide?
PuratrOnic™ undergoes additional purification steps including sublimation and zone refining to achieve 99.999% metals basis purity, compared to typical reagent grades at 98-99% purity. This eliminates virtually all trace metal contaminants that could interfere with sensitive applications.
2. How should this material be stored to maintain its purity?
Store in the original container under inert gas (argon or nitrogen) at room temperature, away from light and moisture. Once opened, reseal immediately and use within 6 months for optimal purity retention. Avoid storage near oxidizing agents or reducing metals.
3. What analytical methods verify the 99.999% purity claim?
The purity is confirmed through glow discharge mass spectrometry (GDMS) and inductively coupled plasma mass spectrometry (ICP-MS) analysis, which can detect impurities at parts-per-billion levels. Certificate of analysis includes complete elemental impurity profile.
4. Are there any special handling precautions for this ultra-high purity material?
Use powder-free nitrile gloves and PTFE or stainless steel tools to prevent contamination. Work in a clean environment (Class 100 or better) and avoid glassware that may leach metals. Never use metal spatulas as they can introduce impurities.
5. What particle size range does this mercury(II) sulfide powder have?
The material features a controlled particle size distribution primarily between 1-5 microns, with 90% of particles under 10 microns. This uniformity ensures consistent reactivity and dispersion in various applications without requiring additional milling.
