Toby (pictured) is doing a great job for us in Shoreham testing samples for metals contamination using XRF (X-Ray Fluorescence). XRF is highly sensitive to metallic elements, however, the XRF from QROS can also detect the lighter elements such as Ca, Mg, Al, Sulphur and Chlorine, which can be useful for Sulphate estimations. The use of more in-situ and on-site testing is one of a number of measures that we are undertaking to reduce the carbon footprint of our activities. If we reduce the number of samples being sent to the laboratory for testing, this contributes towards reducing the carbon footprint of our overall activities.



X-ray fluorescence (XRF) is the emission of characteristic “secondary” (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis, particularly in the investigation of metals, glass, ceramics and building materials, and for research in geochemistry, forensic science, archaeology and art objects such as paintings and murals.
