Comparing Fusion, Crushing, and Pelletising Techniques in XRF Labs
In X-ray fluorescence (XRF) laboratories, the choice of sample preparation method determines analytical precision and accuracy by governing sampling representivity, physical stability, and matrix effects. Because the XRF spectrometer interrogates only a small volume of material, any heterogeneity introduced or left unresolved during preparation is expressed directly in the reported result. Sample preparation techniques therefore function as analytical controls, each addressing a specific limitation associated with solid samples rather than serving as interchangeable processing steps. Crushing, pelletising, and fusion differ in how much variability they suppress, how much effort they require, and which sources of uncertainty remain present at the point of analysis. Comprehending such dif

Optimizing Fusion Flux Ratios for Precise XRF Sample Preparation
Data quality in X-ray fluorescence (XRF) analysis is inseparable from sample preparation quality. Fusion-based preparation removes mineralogical and particle size effects only once a sample is fully dissolved into a uniform glass. The fusion flux ratio sits at the centre of this process, defining dissolution capacity, matrix dilution, and glass stability, all of which directly influence analytical precision and repeatability, and govern measurement accuracy across major, minor, and trace elements. When carefully optimized for the material under analysis, the fusion flux ratio becomes one of the most effective controls available for improving XRF performance.

Step-by-Step Pelletising Workflow for XRF Analysis
X-ray Fluorescence (XRF) analysis depends as much on sample preparation as it does on the performance of the spectrometer itself. Before any measurement takes place, the physical condition of the sample determines how X-rays interact with the material and how consistent the resulting data will be. Pelletising is widely used because it converts loose powder into a stable, uniform form that can be analysed repeatedly under controlled conditions. When pellet preparation follows a clear and logical sequence, many common sources of variability can be reduced, such as particle size differences, uneven density, and surface irregularities, leading to more dependable XRF measurements.
