Stable Isotope Analysis of H₂O (Liquid Water)

The contract seeks precision measurement of stable oxygen-18 and deuterium isotopes in liquid water samples using cavity ring-down spectroscopy or isotope ratio mass spectrometry, primarily to support hydrological and climate research efforts. The work is tied to NOAA under the Department of Commerce and falls under NAICS code 541380, indicating it is a scientific research and development service. Performance is designated for Boulder, Colorado, where sample analysis will be conducted under strict analytical protocols to ensure high accuracy and reproducibility for scientific applications. This is a subcontract opportunity with a response deadline of May 12, 2026, at 4:00 PM, and was posted on May 6, 2026. No set-aside preferences or organizational type restrictions are specified, making it open to qualified service providers. The absence of a designated point of contact and detailed administrative information suggests that proposers should rely on the posted SAM.gov link for full submission guidelines and technical expectations. The focus remains on delivering high-quality isotopic data critical for advancing understanding of water cycle dynamics and climate patterns.
