Description
This is a Request For Information - This synopsis is for information and planning purposes only and is not to be construed as a commitment by the Government. No contract will be awarded as a result of this Sources Sought announcement. The United States Geological Survey, Office of Acquisition and Grants is soliciting information from qualified sources; the results of this announcement will be evaluated to determine if there are businesses capable of performing the proposed work. The US Geological Survey, Office of Acquisition and Grants seeks responses from vendors that possess the capability to perform high-precision, MIni CArbon DAting System (MICADAS) analyses of small (The contractor shall perform radiocarbon analyses using the latest MICADAS technology, which features a versatile accelerator mass spectrometer that can measure 14C in samples either as graphite (after sample preparation) or more rapidly as CO2 gas (after purification). Gas analysis allows for a smaller sample size and faster throughput, but at lower precision than traditional graphite analysis. Recent studies (Zander et al., 2020) show evidence that dating more samples at lower precision can lead to more accurate age models for similar cost as models developed with fewer, higher-precision ages. Samples from lakes along the West Coast of the United States and Alaska will be processed and analyzed according to the technical procedures specified below:(a) The contractor shall pretreat organic samples for removal of exogenous carbon (Olsson, 1986). The sample is treated with 1N HCl for 30 minutes at 60°C, then 1N NaOH for 30 minutes at 60°C, and again for 30 minutes at 60°C, with an 18.2 M¿ water rinse between each step. The sample is then dried in a freeze-drier or an oven at 60°C. For very small samples, a less-rigorous treatment will be followed to avoid destroying the material. Very small samples will be treated at 40°C with with 0.5¿mol¿L¿1¿ HCl, 0.1¿mol¿L¿1¿NaOH, and 0.5¿mol¿L¿1...
