X-ray fluorescence technology provides one of the most accurate analytical methods for the determination of the elemental composition of many types of materials. It is non-destructive and reliable, requires no, or little, sample preparation and is suitable for solid, liquid and powdered samples. It can be used for a wide range of elements, from sodium to uranium and provides detection limits at the ppm level and can measure concentrations of up to 100%.

Types of samples include oils and fuel, plastics, rubber and textiles, pharmaceutical products, foodstuffs, cosmetics and body care products, fertilizers, minerals, ores, rocks, sands, slags, cements, heat-resistant materials, glass, ceramics, semiconductor wafers; the determination of coatings on paper, film, polyester and metals; the sorting or compositional analysis of metal alloys, glass and polymeric materials; and the monitoring of soil contamination, solid waste, effluent, cleaning fluids, sediments and air filters.

It is also useful for small particle analysis. One customer of MAX, a bulk chemical manufacturer, discovered microscopic, non-magnetic particles of a metallic appearance in one of their products. On examination of 3 of these ~ 500-800 micron particles, with the Spectro (www.spectro.com) XEPOS XRF instrument, they were found to contain Cr, Fe, and Ni - in other words a stainless steel.
