IR System Add-ons (Microplastics)

The U.S. Food and Drug Administration is procuring a counter-propagating mode upgrade for its existing Photothermal mIRageLS microscope under a sole-source, non-competitive acquisition, justified by the exclusive ownership of Optical Photothermal Infrared (O-PTIR) technology by Photothermal Spectroscopy Corp. (PSC), the only entity capable of delivering full system compatibility with the FDA’s current instrumentation. This upgrade, intended for the detection of microplastics and nanoplastics in human foods, requires seamless integration into the existing software platform and must enable electronic switching between co- and counter-propagating imaging modes with sub-500 nm spatial resolution, a capability uniquely provided by PSC through its patented technologies. The acquisition is constrained to PSC due to its exclusive patent portfolio, manufacturer-specific authorization requirements for installation and qualification, and the impossibility of achieving technical functionality with any other vendor. As a registered small business with CAGE code 83PQ8 and NAICS code 334516, PSC is the sole responsible source, and the procurement is structured as a Firm-Fixed-Price purchase order under simplified acquisition procedures, valued between $25,001 and $250,000. Performance is to occur at the FDA’s facility in College Park, Maryland, with acceptance criteria centered on functional integration, software compatibility, and manufacturer-authorized commissioning. No competition is permitted or practicable, and all responders must demonstrate formal authorization from PSC to distribute and service the O-PTIR system, alongside proof of small business status and prior contract performance. The presolicitation was issued on July 30, 2026, with a deadline for capability statements on August 13, 2026, and an anticipated award date no later than September 9, 2026. Communication and submissions are handled exclusively via email to designated FDA contracting personnel, with no formal contract clauses, detailed pricing, or logistical specifications provided at this stage.
