Oxygen Isotope (δ¹⁸O) Analysis

The contract seeks specialized stable isotope ratio mass spectrometry services to analyze the oxygen isotope composition of cellulose and whole wood samples, with the goal of reconstructing historical climate conditions. The work requires precise laboratory analysis using isotope ratio mass spectrometry (IRMS) to measure δ¹⁸O values, which serve as proxies for past temperature and hydrological patterns. Samples must be prepared and processed according to established protocols to ensure data accuracy and reproducibility for climate research applications. This subcontract is posted under NAICS code 541380 and is issued by the Department of the Interior’s Office of Acquisition Grants. The solicitation was made public on August 5, 2026, with a firm response deadline of August 13, 2026. The place of performance and detailed contact information are not specified, indicating flexibility in where the analytical work will be conducted. The contracting office is seeking qualified providers capable of delivering high-quality isotopic data within the specified timeframe, with no set-aside provisions identified for small businesses or other categories.
