Choosing the Ideal Fusion Flux for Consistent XRF Sample Preparation
Consistent, high-quality XRF results rely on far more than just the performance of the spectrometer. The accuracy of the data begins with the way the sample is prepared. Fusion XRF sample preparation is a reliable method for generating reproducible data from oxide, mineral, and geological samples, as it converts powders into homogeneous glass beads that minimize particle-size and mineralogical effects. At the centre of that process lies the fusion flux, a borate-based chemical reagent that lowers the sample’s melting point and enables complete dissolution during fusion. Its chemistry, purity, and handling determine whether the sample fully dissolves and how uniform each bead will be. Selecting the right fusion flux

Selecting and Calibrating Grinding Mills for XRF Sample Pulverisation
In X-ray fluorescence (XRF) analysis, accuracy begins with preparation. The way a sample is ground, mixed, and homogenized dictates how faithfully its elemental composition can be measured. To ensure consistency, the sample must be reduced to a fine, uniform powder where each particle contributes equally to the XRF signal. Should particle size or texture vary, X-rays can be absorbed and scattered unevenly, leading to unreliable results.
Pulverisation refines material to below 75 micrometres, or finer than 50 micrometres for high-precision analysis. Consistent pulverisation performance depends on selecting a grinding mill suited to the material and maintaining its calibration over time. When both are controlled, the outcome is a contamination-free powder and dependable data for XR

Advanced Pelletising Techniques to Improve XRF Sample Homogeneity
The homogeneity of a sample is an important factor that governs the accuracy and reliability of the results obtained through X-ray fluorescence (XRF) analysis. Even subtle variations in density, particle size, or surface smoothness can alter the ways X-rays are absorbed and emitted, leading to inconsistent intensity ratios and calibration drift. While conventional pelletising methods can yield acceptable data, advanced pelletising techniques offer far greater control over sample uniformity and analytical precision. The goal of these techniques is to eliminate small structural inconsistencies that limit sample homogeneity and, in turn, the quality of the XRF analysis.
