Process steps: Position the analyzer against a circuit board surface Trigger the device to stimulate fluorescence from target elements Detect emitted energies (gold around 9.71 keV, silver around 22.1 keV, palladium around 21.2 keV) Convert signals to concentration values displayed in ppm or percentage Typical analysis times range from 1–3 seconds for a ...
Testing Process (cable recycling): Surface prep (about 30 seconds): Remove insulation to expose clean metal. Dirt and oil block X-rays; a clean surface yields accurate readings. Position the analyzer window against the metal (about 5 seconds). ...
Traditional X-ray Photoelectron Spectroscopy (XPS) is a cornerstone technique for investigating the surface chemistry of materials. However, conventional XPS systems operate under ultra-high vacuum (UHV) conditions — a controlled environment necessary for accurate measurements, but far removed from the pressures and reactive conditions most materials experience in real-world ...
The chemistry of a material’s outermost nanometres often determines its functional performance, making accurate surface characterisation vital for modern materials research. Yet, analysing these nanometre-scale layers is inherently challenging, as many surface-sensitive chemistry techniques, like AES, can modify the material or disturb its native chemical composition and techniques like EDX ...
Introduction Surface finish tells us a lot about how a part will perform, whether it will seal properly, move smoothly, or wear too soon. Measuring surface roughness is the science of quantifying those tiny peaks and valleys on a material’s surface. Over the years, this field has evolved from contact-based tools to advanced non-contact optical metrology techniques that deliver microscopic ...
