XRF Sample Preparation: An Important Step for Accurate Analysis

Accurate XRF analysis depends on careful sample preparation. Traditionally, this process requires a series of time-consuming and precise steps: drying samples to constant weight, blending them with flux and additives, controlling fusion temperatures, casting beads, and ensuring repeatability across multiple operators. Each stage plays a role in producing reliable results, but together they create a workflow that is both complex and prone to variability.

Simplified XRF Sample Preparation with Navas Instruments

Navas Instruments redefines this process. Our patented fusion fluxer eliminates unnecessary complications by integrating and automating the essential steps into a single streamlined workflow:

• No sample drying required — analysis begins directly with the raw sample.
• No casting step — beads are formed and ready without extra handling.
• Automated LOI/LOF measurement — every sample is precisely recorded without additional procedures.
• Controlled addition of non-wetting agent — a small amount, diluted in water, is introduced only at the end of the fusion cycle, after the final bead weight is taken.

By removing unnecessary steps, the instrument minimizes human error, improves reproducibility, and frees laboratory staff to focus on higher-value work. The result is a more efficient lab with less repetitive handling and more reliable outcomes.

The outcome is consistent, high-quality glass beads for XRF analysis—achieved faster, with less effort, and at lower cost.
