Handheld X-Ray Fluorescence for ERDC GSL

The document outlines the requirements for a Handheld-X-Ray Fluorescence (XRF) spectrometric device for detecting elemental concentrations in soils and sediment deposits. The device must be lightweight (under 3 lbs), compact (under 195 in³), and feature a Gold (AU) anode with specific kV, uA, and wattage. Key specifications include a 4mm fixed collimated beam, a Silicon Drift Detector (SDD) with a minimum 50mm² active area, and 140 eV energy resolution. The XRF must detect a comprehensive list of elements across various groups, including alkali metals, alkaline earth metals, metalloids, post-transition metals, transition metals, lanthanides, and reactive non-metals, with the option for additional library standards. It requires auto-calibration, multi-integrated cameras, an Android-based OS, and PC software for data analysis and report generation in PDF and CSV formats. Data transfer options include wireless, USB, and SD. The device needs a 1.2GHz processor, 2GB RAM, 16GB internal storage, 32GB external storage, built-in Wi-Fi, Bluetooth, and GPS capabilities. It must operate between 10°F and 130°F, have user-level password protection, and administrative privileges. Power will be supplied by hot-swappable batteries (rechargeable within the device or via an external charger) and AC power. Required accessories include a battery charger, carrying case, various test stands, detection standards, on-site training, and a customer care program. Additional submittal requirements include manufacturer and submitter letters verifying approval as a primary or reseller and direct in-house technical support, along with product specifications. Shipping costs must be included in the quote, and delivery is required by March 16, 2026, to the GSL-Airfields and Pavements Branch in Vicksburg, MS.
