Handheld XRF analyzer featuring 55 kV x-ray tube (55 kV, 100uA, 5.5W)

Handheld XRF analyzer featuring 55 kV X-ray tube (55 kV, 100 uA, 5.5 W) for performance on Priority Pollutant and RCRA metals Cd, Ba, Sn, Sb and Ag. The device needs to be engineered with a mostly metallic, tapered ergonomic design ideal for heat dissipation and field ruggedness – essentials for high volume in field soil testing requirements. High resolution, high count rate silicon drift detector (25 mm2 SDD, 135 eV at 5.95 Mn K-alpha line, at > 90% live time, 250k cps) for fast and precise analysis of soils, rocks, ores and other non-alloy sample types. Three separate beam settings for possible detection limits on Cd, Ba, Ag, Sn and Sb while also achieving low detection limits from P to Pb. Analyzer auto-calibrates and checks calibration on external 316 stainless test material (included). Analyzer features protective mesh covering SDD detector to eliminate accidental detector punctures. Analyzer must include integrated micro and macro camera for photo documentation of tests and reading QR codes for recording sample identification for chain of custody. Must be usable on Google-powered, Android operating system. Must include wireless and Bluetooth built in for easy connectivity to other devices and GPS connectivity via an external GPS/Bluetooth to allow the device software to seamlessly tag results with high-resolution spatial coordinates. 55 kV for best performance on: Cd, Ba, Ag, Sn, Sb Plus multiple beam element package: P, S, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Zr, Mo, Hg, Pb, Tl. PC Software for PC operation, import/export of results, data management. Each system must include: 2 Li-Ion batteries, battery charger, ruggedized carrying case, spare Prolene windows, operations manual, 1 year manufacturing warranty, as well as, a Silicone Sleeve (small Screen), Benchtop stand with built-in interlock, fans, and power supply, and a handsfree stand for in-situ soil analysis.
