ULTIM INFINITY 170 WITH SW/HW EDS or Equal

The United States Geological Survey (USGS), specifically its Geology, Geophysics, and Geochemistry Science Center in Denver, Colorado, is conducting market research to identify potential suppliers for an Energy Dispersive Detector (EDS) upgrade compatible with the Oxford Instruments Ultim Infinity 170 system. This effort supports the Mineral Resource Mission Area and aims to enhance the laboratory’s capabilities in analyzing critical minerals and energy resources at a micro-scale. The EDS in question must meet stringent physical, functional, and performance criteria, including a sensor size of at least 150 mm2, compatibility with existing FEI 450 Quanta FESEM and Oxford control hardware, the ability to detect elements from beryllium through uranium, and high spectral resolution with minimal drift. Software integration is essential for automated workflows, data storage, quantification, phase analysis, and pulse pile-up correction. This announcement is a sources sought notice for market research only; it is not a request for proposals or bids and no contract will be awarded based on responses to this notice. Businesses interested in this opportunity must demonstrate their ability to meet the specified technical requirements, provide details on product origin with a preference for U.S. manufacturing under the Buy American Act, and disclose their business size and socioeconomic status as defined under NAICS code 334516. Submissions must include product specifications, company information, and registration details in SAM.gov. Responses are voluntary, will not be compensated, and must be submitted by May 11, 2026.
