Product Overview

Lithium metaborate (LiBO₂) is a high-purity, anhydrous flux specifically formulated for X-ray fluorescence (XRF) and inductively coupled plasma (ICP) sample preparation. With a minimum assay of 99%, this dried reagent ensures optimal fusion of refractory oxides, silicates, and minerals without introducing contaminants. Its low melting point (845°C) enables rapid and complete dissolution of samples, producing homogeneous glass beads for accurate elemental analysis. The reagent’s hygroscopic nature is mitigated through careful drying, ensuring consistent performance across applications. Unlike lithium tetraborate, this metaborate variant offers superior solubility for certain matrices while maintaining thermal stability. Its fine particle size distribution promotes uniform mixing with sample powders, reducing segregation during fusion. The product is packaged in moisture-resistant containers to preserve purity during storage and handling.

FAQs

1. What is the melting point of this lithium metaborate?

The melting point is approximately 845°C, making it suitable for most flux fusion applications where lower temperatures are preferred compared to other borate fluxes.

2. Can this be used as a standalone flux or requires mixing?

While it can function as a standalone flux for many samples, it’s often combined with lithium tetraborate in specific ratios to optimize fusion characteristics for particular sample types.

3. How does the purity level affect analysis results?

The 99% minimum purity ensures minimal background interference in spectroscopic analysis, particularly important for trace element detection where even minor impurities could skew results.

4. What’s the recommended storage condition to maintain quality?

Store in a tightly sealed container in a cool, dry place. Despite being dried, the product can absorb moisture over time, which may affect its performance as a flux.

5. Is this compatible with platinum crucibles?

Yes, lithium metaborate is compatible with platinum crucibles, though proper cleaning procedures should be followed to prevent cross-contamination between fusions.
