Determining elemental compositions on-site from far-flung mining and geological field operations is a substantial challenge. The Spectroscout portable energy dispersive x-ray fluorescence (ED-XRF) analyzer provides accurate results in real-time. Replete with a shoulder strap, the 12 kg unit is encased in rugged housing with its x-ray source protected. It includes a large sample compartment, an x-ray tube, an onboard processor and a high-yield battery pack. An optional integrated video system allows for precise spot testing and image storage. Only one sample is needed for calibration, which takes only five min. Sample analysis turnaround time ranges from 10 to 15 min. Spectro Analytical Instruments Gmbh
