Combustion Analyzer

The United States Department of Agriculture (USDA) is seeking a combustion analyzer for a research lab. The analyzer should be capable of measuring element concentration ranges, including C, N, S, O, and H, with specific precision requirements. The acquisition is set aside for small business concerns, and all responsible sources may submit a quotation. To be considered for award, offerors must submit a firm fixed price quotation, SF-1449, Sam.gov Unique Entity ID, and capability statement and/or technical documentation. * The required specifications include: * Element concentration range: C up to 20 mg abs, N up to 15 mg abs, S up to 3 mg abs, O up to 6 mg abs, and H up to 3 mg abs * Precision: Elemental performance (external precision, 1σ) < 0.1 % for C, N, S, and O * Isotope ratio performance (external precision, 1σ): δ13C: 0.1 ‰, δ15N: 0.15 ‰, δ34S: 0.2 ‰, δ18O: 0.3 ‰, δ2H*: 3 ‰, δ2H* (HDChrome): 0.5 ‰
