Product Overview
This Arsenic(III) oxide from the Puratronic™ line represents the pinnacle of purity for arsenic compounds, with a certified 99.996% metals basis purity excluding antimony. The product undergoes rigorous purification processes to eliminate trace metallic contaminants, with antimony content individually reported for each batch to ensure consistency in high-sensitivity applications. The material presents as a fine, white to off-white crystalline powder with exceptional homogeneity, critical for applications where uniform dispersion is required. Its ultra-low impurity profile makes it particularly valuable in semiconductor manufacturing where arsenic doping demands precise control over impurity levels. The product’s high purity also translates to minimal background interference in spectroscopic analysis, making it a preferred choice for calibration standards in atomic absorption and ICP-MS techniques. Packaged under inert conditions to prevent oxidation, the material maintains its specified purity throughout its shelf life when stored as recommended. The Puratronic™ grade designation indicates this product meets the most stringent purity requirements for advanced materials research and industrial applications where trace impurities could compromise results.
FAQs
1. What is the significance of the “metals basis excluding Sb” specification?
The metals basis excluding Sb specification indicates that the 99.996% purity measurement excludes antimony content, which is separately quantified and reported. This allows users to account for antimony as a known impurity rather than having it affect the overall purity calculation.
2. How does the Puratronic™ grade differ from standard reagent grades?
Puratronic™ grade represents the highest purity tier available, with significantly lower trace metal impurities compared to standard reagent grades. While reagent grades typically have purity in the 98-99% range, Puratronic™ materials are certified to 99.99%+ purity with individual impurity analysis provided.
3. What precautions should be taken when handling this high-purity arsenic oxide?
Despite its high purity, arsenic(III) oxide remains highly toxic. Always handle in a certified fume hood wearing appropriate PPE including nitrile gloves, lab coat, and respiratory protection. The material should be stored in its original container with secondary containment to prevent accidental exposure.
4. Is this product suitable for use in food or pharmaceutical testing?
While the product meets exceptional purity standards, it is not certified for food or pharmaceutical applications. The material is intended solely for laboratory and industrial use where arsenic’s toxic properties are properly controlled.
5. How should this product be stored to maintain its purity?
Store the unopened container in a cool, dry place away from direct sunlight and incompatible materials. Once opened, reseal immediately under inert atmosphere if possible, and use dedicated, clean tools to prevent contamination from moisture or other laboratory chemicals.
