KCCAMS | W. M. Keck Carbon Cycle Accelerator Mass Spectrometer Facility

The KCCAMS facility offers radiocarbon (¹⁴C) measurements, alongside analyses of %C, %N, δ¹³C, and δ¹⁵N, in support of carbon cycle research. It supports researchers at all University of California campus locations and also accepts samples from US/international researchers not affiliated with the UC system. The facility consists of the KCCAMS sample preparation laboratory and four laboratories focused on terrestrial/atmospheric, marine, and paleoclimate research. Samples handled routinely include organics (plant material, bone), carbonates, water, carbonaceous aerosol (bulk and elemental/black carbon), carbon dioxide, and methane.

Please note that the facility only accepts samples in batches of at least 10 samples of the same type (e.g., organics).
