Supply of Energy Dispersive Spectrometer (EDS) Detector

The contract calls for the supply of a new or equivalent energy dispersive spectrometer (EDS) detector, specifically the Oxford Instruments Ultim Infinity 170 or an equally capable alternative, to be integrated into existing electron microscopy systems at the USGS Denver laboratory. This equipment is essential for conducting high-resolution mineralogical analysis, enabling detailed elemental composition mapping and identification critical to geological research and environmental assessments. The detector must be fully compatible with current instrument platforms and capable of delivering precise, reliable data under demanding analytical conditions. The solicitation is structured as a subcontract with a response deadline of May 11, 2026, at 8:30 PM, and is classified under NAICS code 334516, indicating its focus on instrumentation for scientific measurement and control. The contracting office falls under the Department of the Interior’s Office of Acquisition Grants in Denver, with no specified place of performance other than the USGS Denver facility. Although no set-aside provisions are indicated, the requirement demands technical equivalence to the specified model, requiring proposers to demonstrate performance parity and compatibility without reliance on a single vendor. The urgency reflects the lab’s operational need to maintain and enhance analytical capacity for mineralogical studies.
