EDXRF Spectrometers

Energy dispersive X-ray fluorescence (EDXRF) spectroscopy provides one of the simplest, most accurate and most economic analytical methods for the determination of the chemical composition of many types of materials. The technique is generally non-destructive, requiring little if any sample preparation, and is suitable for almost all sample types. EDXRF analysis can be employed to measure a wide range of atomic elements, from sodium through uranium, while providing detection limits from low parts-per-million (ppm) to high weight percent (wt%). In addition to elemental analysis, EDXRF may be used to measure the thickness and composition of multi-layer thin films.

Typical uses of EDXRF include the analysis of petroleum oils and fuel, plastic, rubber and textiles, pharmaceutical products, foodstuffs, cosmetics and body care products, fertilizers, geological materials, mining feeds, slags and tails, cement, heat-resistant materials, glass, ceramics, catalysts, wafers; the determination of coatings on paper, film, polyester; metals and alloys, glass and plastic; forensics and pollution monitoring of solid waste, effluent, cleaning fluids, pools and filters. X-ray transmission is employed to measure sulfur (S) in crude oil and marine bunker fuel.
