The KCCAMS facility routinely accepts a wide range of sample types, including charcoal, wood, seed, carbonates, animal remains, CO2<\/sub>, and bulk aerosol. The minimum sample size for a routine 14<\/sup>C measurement is 0.8-1 mg C. Smaller sample sizes (10-100 ug C) can be analyzed at reduced precision upon special request.<\/p>\n\n\n\n Other sample types (including DOC, DIC, OC\/EC aerosol fractions, and CH4<\/sub>) may be analyzed upon special request and\/or as part of research collaborations with KCCAMS faculty and researchers.<\/p>\n\n\n\n *For low-carbon organic material, the carbon content can vary widely, and no estimate for the preferred minimum sample size can be given.
