W. M. Keck Carbon Cycle Accelerator Mass Spectrometer (KCCAMS) Facility

UC Irvine’s KCCAMS radiocarbon (14C) measurement facility is dedicated to supporting carbon cycle research. It combines the KCCAMS sample preparation laboratory that accepts samples from domestic and international researchers and three research laboratories that process samples for terrestrial/atmospheric, marine, and paleoclimate research.
