Summary
AI-generated · Dec 18, 2025A qualified laboratory is sought to perform simultaneous measurements of delta-18O, delta-13C, and delta-15N in powdered CaCO3 samples derived from biogenic materials such as coral skeletons, mollusk shells, and crustacean exoskeletons, using stable isotope ratio mass spectrometry (SIR-MS). The engagement covers a base year with four option years (five years total) and is expected to process between about 2,000 and 5,000 samples over the contract period.
USGS staff will hand-deliver samples to the laboratory and require hands-on assistance with sample handling, including weighing samples and standards, loading into reaction vessels, encapsulating in tin boats, arranging into sample trays, and operating the IRMS under supervisor oversight. The lab must be accessible for coordination with USGS scheduling and must be able to demonstrate capability and experience to perform these tasks. Respondents should confirm their capabilities, business type, small-business status, and include proof of UEI and SAM registration.
