Product Name – Lithium metaborate, Puratronic™, 99.997% (metals basis) Quantity/Pack Size – 500g, 100g, 25g Form – Powder Grade – Puratronic™ (99.997%) Application – XRF flux, sample preparation
Product Overview
This Puratronic™ lithium metaborate delivers exceptional 99.997% purity (metals basis), making it ideal for demanding analytical applications where trace metal contamination must be minimized. The anhydrous powder form ensures consistent performance as a fluxing agent in X-ray fluorescence (XRF) sample preparation, providing complete decomposition of samples while maintaining ultra-low background interference. Its controlled particle size distribution enhances fusion efficiency, while the rigorous purification process eliminates common contaminants like iron, sodium, and potassium that could skew analytical results. The material’s high lithium content (theoretical 16.5%) ensures optimal fluxing properties, enabling complete dissolution of refractory oxides at lower temperatures compared to conventional fluxes. Packaged under inert conditions to prevent moisture absorption, this grade maintains its reactivity and purity throughout storage. The product’s exceptional clarity in fused beads reduces matrix effects, improving accuracy in quantitative elemental analysis across geological, environmental, and industrial samples.
FAQs
1. What is the maximum operating temperature for this lithium metaborate flux?
This Puratronic™ grade remains stable up to 1000°C, though typical XRF fusion applications use temperatures between 950-1050°C for complete sample dissolution.
2. How does this compare to standard lithium tetraborate fluxes?
Lithium metaborate offers lower melting point (845°C vs 930°C) and better dissolution of basic oxides, while this Puratronic™ grade provides superior purity compared to standard technical grades.
3. Can this be used with platinum crucibles?
Yes, this high-purity grade is compatible with platinum labware, though we recommend verifying your specific fusion protocol as some sample matrices may require additional precautions.
4. What is the typical shelf life when stored properly?
When kept in the original sealed container at room temperature, the product maintains its specified purity for at least 24 months from date of manufacture.
5. Does this contain any anti-caking agents or additives?
No, this Puratronic™ grade contains no additives, binders, or anti-caking agents that could introduce contaminants to your analysis.
