Product Name – Lithium tetraborate, Puratronic™, 99.998% (metals basis) Quantity/Pack Size – 1kg, 100g, 25g Form – Powder Grade – Puratronic™ (99.998%) Application – Flame atomic absorption, XRF flux, high-purity synthesis
Product Overview
This Puratronic™ grade lithium tetraborate delivers exceptional 99.998% purity (metals basis), making it the preferred choice for critical analytical applications where trace impurities could compromise results. The anhydrous, free-flowing powder form ensures consistent performance in flame atomic absorption spectroscopy, X-ray fluorescence (XRF) flux preparation, and specialized synthesis requiring ultra-low metal contamination. Unlike standard grades, this material undergoes rigorous purification processes to eliminate transition metals and other interfering elements, providing researchers with reliable baseline data. Its high boron content and lithium stabilization create a stable flux matrix that enhances sample fusion while minimizing background interference. The product’s hygroscopic nature requires careful handling, but its purity profile justifies the additional precautions for sensitive applications. Each batch undergoes comprehensive metals analysis to verify the 99.998% specification, with certificates of analysis provided for quality assurance. The material’s consistent particle size distribution further ensures reproducible results across different analytical techniques.
FAQs
1. What is the difference between Puratronic™ and standard lithium tetraborate grades?
Puratronic™ undergoes additional purification steps to achieve 99.998% metals basis purity, eliminating most transition metal contaminants that could interfere with sensitive analytical techniques. Standard grades typically contain higher levels of iron, copper, and other metals that may affect detection limits in trace analysis.
2. Can this product be used directly for XRF sample preparation without further purification?
Yes, the 99.998% purity makes it suitable for direct use as an XRF flux without requiring additional purification steps. However, we recommend pre-drying the material at 105°C for 2 hours before use to remove any absorbed moisture that could affect fusion characteristics.
3. What storage conditions are recommended to maintain the product’s purity?
Store in a tightly sealed container under inert gas (argon or nitrogen) in a desiccator to prevent moisture absorption. Exposure to ambient humidity can lead to caking and potential contamination from atmospheric particulates over time.
4. Are there any known incompatibilities with common laboratory materials?
The material reacts violently with strong acids and should not be stored near acidic reagents. It’s also incompatible with strong oxidizing agents. Use glass or PTFE containers for storage and handling to prevent potential reactions with metal containers.
5. What documentation is provided with each batch?
Each package includes a certificate of analysis detailing the metals basis purity verification, trace element analysis (typically <10 ppm for most transition metals), and physical properties like particle size distribution and moisture content.
