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...

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...

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...
