Can XRF Machines Measure Silver Purity at 60%?
Silver purity defines the percentage of elemental silver (Ag) present in a metal sample. Fine silver—marked as .999—contains 99.9% pure silver, making it suitable for bullion bars and select coins. Sterling silver consists of 92.5% silver blended with 7.5% copper or othe...Read more -
Efficient Mining of Niobium with Handheld XRF Analyzers
Niobium remains a strategic mineral in energy storage, superalloy production, and advanced technology sectors. Efficient niobium deposit exploration requires rapid identification of niobium-rich zones within vast carbonatite or alkaline igneous formations. High-grade nio...Read more -
Analysis of Zircon Concentration in Granite by X-Ray Fluorescence
Zircon is a chemically robust accessory mineral essential for tracing granite petrogenesis due to its ability to retain primary magmatic information during high-grade metamorphism and alteration. In high-silica granites, zircon element ratios (e.g., Zr/Hf, Eu/Eu*, Ce/Ce*...Read more -
Non-Destructive Elemental Analysis of Precious Metals and Jewelry
Jewelers, pawnbrokers, and asset managers confront the challenge of verifying the purity and authenticity of gold, platinum, and silver without harming valuable items. Fire assay and acid scratch tests remove material or cause surface damage, permanently reducing value a...Read more -
How Much Can Be Saved in Rare Earth Mining by Using a Portable XRF Analyzer?
Global rare earth element (REE) demand will reach 315,000 tonnes by 2030, driven by electric vehicle, wind power, and electronics manufacturing. Supply is constrained by limited new discoveries and high entry costs. Efficient rare earth mineral exploration techniques, in...Read more -
X-Ray Fluorescent Spectrometric Determination of Yttrium in Rare Earth Ores
Yttrium rare earth metal is essential for jet engines, semiconductors, high-performance ceramics, and phosphors in LED displays and lasers. Yttrium doped alloys and oxide nanoparticles provide superior anticorrosion, antibacterial, and optical properties for clean energy...Read more -
Energy Dispersive X-Ray Fluorescence Spectroscopy Systems
An energy dispersive x-ray fluorescence spectroscopy system (EDXRF system) detects elemental composition by measuring the characteristic x-rays emitted from a sample during irradiation with a primary x-ray beam. An EDXRF analyzer uses an energy dispersive detector to sep...Read more -
Rubidium Measured by XRF as a Predictor of Soil Particle Size in Limestone and Siliceous Parent Materials
Soil particle size distribution shapes hydraulic conductivity, compaction, and pore structure. Water retention curves shift as sand, silt, and clay fractions vary; sandy soils drain rapidly, providing limited moisture, while clay soils retain water but restrict aeration....Read more -
How to Determine Bromine Content in Soil through X-Ray Fluorescence Analysis?
The vadose zone is defined as the unsaturated soil region between the ground surface and the water table. This layer governs vadose zone water flow, contaminant migration, and overall soil health. Precise bromide content in soil is vital for subsurface transport studies,...Read more -
How Can XRF Spectroscopy Accurately Detect Selenium Content in Cadmium Red Pigment?
Cadmium red pigment is a class of inorganic pigments formed as solid solutions of cadmium sulfide (CdS) and cadmium selenide (CdSe). The precise selenium content (x) dictates the color, shifting the hue from orange (low Se) to deep red (high Se) by lowering the bandgap f...Read more -
Arsenic Contamination Detection in Food Using X-Ray Fluorescence Analyzer
Arsenic occurs naturally in minerals, groundwater, and sediments. Industrial activities and mining further elevate arsenic in soil and water. Food crops absorb arsenic from these sources, leading to contamination. Inorganic arsenic is highly toxic; chronic exposure cause...Read more -
Doping Concentration Analysis in Germanium Semiconductors
Doping directly alters germanium’s carrier concentration, resistance, and threshold voltages. Semiconductor-grade control of phosphorus, antimony, arsenic, and boron content must reach sub-ppm for functional microelectronic and photonic devices. Precise adjustment of pho...Read more
