Oxford Instruments from the United K i n g d o m a n d United Scientific have Oxford XRF analysers available from United Scientific can easily and quickly adjust the calibra- tion with site-specific samples or create and use custom calibration settings for specific requirements. The data can be combined with GPS location information to further boost the productivity for explo- ration, mine mapping and environmental screening.

The unit delivers the versatility of a lab- oratory, right there in the field, enabling fast and reliable analysis of the widest vari- ety of materials, including trace elements and light elements (from magnesium to uranium). It features a large area, silicon drift detector, optimised for mining and soil applications, providing fast analysis, even when measuring light elements, cou- pled with detection limits down to 1 ppm for important metals. At the exploration and planning stages of the mining operation it is important to fully understand the geology of a site. The Mining Analyser allows potential sites to be investigated more thoroughly with minimal invasion, yet quickly and with extreme confidence, throughout the min- ing cycle. The Mining Analyser offers significant savings in analysis costs, as samples can be measured on-site, immediately, with little or no preparation. For total confidence in results and full traceability, operators

recently joined forces to dis- tribute Oxford’s range of portable and benchtop analysers for the mining and metals sector. Oxford Instruments has

The X-MET 7500 series is equipped with a large and bright touch screen, operat- ing even in the harshest environments. It clearly displays the analysis results as a list of compounds or in an elemental form, configured by the operator. The smart and intuitive graphical user interface is easy to learn and simple to operate, similar to that of a mobile phone. The unit requires no external power and can operate for up to 12 hours on a single battery charge, saving on the amount of equipment needed to be carried to often remote locations.

more than 50 years of experience of XRF and over 35 years of experience of por- table XRF technology. The latest version of the handheld XRF is the X-Met 7500 Mining Analyser (pictured above). X-ray fluorescence (XRF) analysis is a proven and valued method for rapidly determining the presence of key minerals at mining sites worldwide. Incorporating the latest detector tech- nology, the X-Met 7500 is said to provide a superb combination of speed, flex- ibility and ease of use for on-site mining and soil analysis.
