X-Ray Fluorescence Analysis (XRF)

Washington Mills Laboratory services offer X-Ray Fluorescence (XRF) Analysis through a fully automated wavelength dispersive x-ray spectrometer. Our technicians are skilled at X-Ray Fluorescence Analysis (XRF) analysis and our XRF instrument is equipped to determine most elements on the periodic table from fluorine to uranium. Want to know what elements are present in your material? Please contact our laboratory if you would like to learn more about our X-Ray Fluorescence (XRF) services for the elemental or chemical analysis of your material.

X-Ray Fluorescence (XRF) Applications:

• Our skilled XRF technicians perform chemical or elemental analysis for a wide range of materials including: Soils • Ceramics • Stone • Pigments • Airborne Particulates • Cement • Steel • Pharmaceuticals • Glass • Textiles • Minerals • Paints • Clays • Cosmetics • Rocks • Chemicals • Polymers • Plastics • Semiconductors • Powder • Many more materials.

X-Ray Fluorescence (XRF) Capabilities:

• Special x-ray tube and optics to give high sensitivity for light elements while maintaining ppm sensitivity for heavier elements. Highly stable electronics allow extremely reproducible analysis, typically 1-2% coefficient of variation.
• Minicomputer with up to date software for fast data processing and on-line interference correction. Operator has a choice of empirical calibration/correction models or optional fundamental parameters model, which allows accurate analysis of materials with a single calibration standard which need not match the unknown.
• Automated elemental analyses are possible on a variety of materials including metal, cement, glass, ceramics, ores, rocks, clays, coal, coke, ash, catalysts, airborne and deposited dusts.
• Samples are prepared for analysis using ground surface, pressed pellet, borate fusion or loose powder techniques
• Qualitative analysis can be performed covering most elements from fluorine to uranium. Element identification is performed by system software which includes the entire NIH database pf 3,000 x-ray emission lines.
• Semi quantitative analysis can be carried out to estimate the concentration of elements present.
• Quantitative analysis can be performed to precisely measure specific elements. Analysis capability extends from low ppm levels for many elements to 100%. Our automation allows for very cost efficient repetitive analysis.
