About this opportunity
The Department of Agriculture Assistant Secretary for Departmental Management issued a Special Notice on September 8, 2026, soliciting a handheld XRF analyzer with response due by September 17, 2026. The device must feature a 55 kV x-ray tube with 100 microampere output and 5.5 watt power consumption, paired with a high-resolution silicon drift detector (25 square millimeter, 135 eV resolution at 5.95 Mn K-alpha, greater than 90 percent live time, 250k counts per second). The analyzer is intended for field detection of priority pollutants and RCRA metals including cadmium, barium, tin, antimony, and silver in soil, rock, ore, and non-alloy samples, with three separate beam settings to achieve low detection limits across a multi-element package from phosphorus to lead. The device must incorporate an ergonomic, metallic tapered design for heat dissipation and field ruggedness, integrated micro and macro cameras with QR code reading capability for chain-of-custody documentation, protective mesh covering the detector, Android operating system compatibility, and wireless, Bluetooth, and GPS connectivity. The system must include auto-calibration against 316 stainless steel test material, PC software for data management and import/export, two lithium-ion batteries, charger, ruggedized case, spare Prolene windows, operations manual, one-year manufacturing warranty, silicon sleeve, benchtop stand with interlock and fans, and handsfree in-situ stand.
Notice text
- 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.
