The U.S. Geological Survey Office of Acquisitions and Grants seeks quotations for an Oxford Instruments Ultim Infinity 170 energy dispersive spectrometer (EDS) or equal for the Geology, Geophysics, and Geochemistry Science Center in Denver, Colorado, with quotations due June 22, 2026, at 2:30 p.m. Mountain Daylight Time and questions due June 17, 2026. This is not a small business set-aside.

The procurement is issued as a Request for Quotations (RFQ 140G0226Q0045) under FAR Part 12 commercial acquisition procedures with streamlined evaluation and award.

The detector must provide sensor size of 150 mm², motorized detector, thin window for beryllium detection, Peltier cooling, element detection from beryllium through uranium, detector resolution per salient characteristics, and throughput handling up to 1,000,000 counts per second. Installation must be completed within 90 days of delivery by a factory-trained and certified engineer. The RFQ includes two line items: Item 00010 for the instrument itself with delivery within 180 days of award, and Item 00020 for installation services with a performance period from August 3, 2026, to April 30, 2027. Both are firm-fixed-price. Warranty must include a minimum one-year manufacturer's coverage of all hardware and software, with FOB Destination shipping included. Award will be made to the lowest-priced, technically acceptable quotation. Vendors must be registered in the System for Award Management (SAM) at submission and award. NAICS code is 334516 (Analytical Laboratory Instrument Manufacturing) with 1,000-employee size standard.
