X-Ray Fluorescence (XRF) Instrument Irvine Medical Products Laboratory (IRVLMP)

The U.S. Food and Drug Administration’s Irvine Medical Products Laboratory is conducting market research through a Sources Sought notice for a benchtop X-Ray Fluorescence (XRF) instrument to support non-destructive elemental analysis of regulated commodities, primarily to detect trace levels of toxic heavy metals like lead and mercury. This Request for Information, identified by solicitation number OC-2026-133864, was posted on May 15, 2026, with responses due by May 21, 2026, and is intended to gather technical data from vendors to inform potential future procurement, not to initiate a contract. Vendors must provide detailed specification sheets demonstrating compliance with specific salient characteristics, including the use of Doubly Curved Crystal x-ray optics, a limit of detection for lead no higher than 0.03 ppm and for mercury no higher than 0.05 ppm, a sample mass range of 0.05 to 3.0 grams, a calibration range extending to at least 10,000 ppm, a physical footprint no larger than 30 inches in width, depth, and height, and operation on standard 110–120V power. Responses are limited to ten pages and must be submitted electronically to freshta.javid@fda.hhs.gov with a designated subject line. The instrument is intended for performance at the FDA’s facility in Silver Spring, Maryland, where government personnel will conduct inspection and acceptance based solely on adherence to the listed technical criteria. Vendors are required to indicate their business size and socioeconomic status, including whether they qualify as small, 8(a), HUBZone, SDVOSB, or WOSB entities, though no UEI or CAGE code is mandated. No formal contract clauses, evaluation factors, pricing, delivery schedules, packaging standards, or payment instructions are included, as this is strictly a pre-solicitation market research action, and no award is anticipated at this time. The NAICS code 334516 applies, and all information must be provided via email, with no online portal involved.
