Understanding How XRF Spectrometers Work

X-ray fluorescence (XRF) spectrometry relies on the interaction between high-energy X-rays and the atoms in a material. When the primary X-ray beam excites a sample, inner-shell electrons are displaced. Electrons from higher energy levels then fill these vacancies, releasing secondary (fluorescent) X-rays with energies characteristic of each element.

By detecting these emissions and measuring their intensities, the spectrometer identifies which elements are present and determines their concentrations. Peak positions indicate elemental identity (qualitative analysis), while peak intensities—calibrated with certified reference materials—provide accurate quantitative results. This approach makes XRF a widely adopted method for elemental analysis across mining, cement, metallurgy, and many other industries.

While the spectrometer delivers precise detection, consistent sample preparation is essential for dependable outcomes. Variability in bead quality can introduce errors, increase rework, and reduce confidence in measurements.

At Navas Instruments, our patented fusion fluxer addresses this challenge by eliminating unnecessary steps such as drying and casting. By automating bead fusion and integrating LOI/LOF measurement, our system simplifies preparation, reduces variability, and produces stable, high-quality glass beads. The streamlined design improves laboratory productivity and enables straightforward automation of the complete workflow—bead handling, XRF analysis triggering, results retrieval, and bead disposal—enhancing both efficiency and accuracy.
