Brand Name Determination Using FAR part 13 (25-521) FE Signed CO_Redacted.pdf

This is a Brand Name Determination document for a sole-source procurement of a Thermo Scientific Dionex ASE 350 Accelerated Solvent Extractor for the Department of Commerce's Fisheries Environmental Chemistry Program (ECP). The specific instrument is critical for analyzing marine biota tissue samples, extracting contaminants, and supporting research projects such as the Puget Sound Estuary Management Project and Southern Resident killer whale contaminant studies. The total estimated cost is redacted, with an estimated delivery date of 09/30/2025.

The procurement justifies the single-source selection based on two key factors: (1) the Dionex ASE 350 is essential to the agency's needs, with analytical methods specifically developed for this exact model over the past 20 years, and (2) compatibility with existing systems, as switching to an alternative would require significant equipment adjustments, labor costs, and potential data comparability issues. The solicitation is issued as an unrestricted, open-source request for quotation (RFQ) with quotes due by 3:00 PM PST/PDT on August 8, 2025, to be submitted electronically to the contracting officer.
