Sample Submission<\/h1>\n
\n
\n

To send samples to Keck-CCAMS at the UC Irvine for analysis, the following steps are required:<\/p>\n

Submitters, and in particular those making their first application, must make contact with the laboratory to discuss their requirements prior to actually submitting samples. Please see the Guidance Document below to identify the appropriate contact(s) for your application (i.e., (1) terrestrial C cycle & atmospheric chemistry, (2) ocean science, or (3) archeology, paleoclimatatology, paleoceanography, paleogenomics or others).<\/p>\n

A submission form plus a sample list provided must be filled out (see guidance document) for each group of samples submitted and sent to us via mail, fax or e-mail. A hard copy of both must also accompany the samples.<\/p>\n

The AMS prep. laboratory is currently equipped to handle routine processing of charcoal, wood, seed, carbonates, animal remains, etc. However, it is up to the submitter to define and select the materials to be dated: for example, since you know your samples far better than we do, it\u2019s your job to pick out the macrofossils or charcoal to be dated from within the sediment or peat matrix. Specialized services such as pollen or foram picking or individual compound separation are not offered. We discourage the dating of bulk soil, peat, or sediments, because those materials are often a mixture of components with widely differing ages. The preferred minimum sample size for a\u00a0<\/span>14<\/sup>C measurement is 1 mg carbon. The sample sizes quoted in the table below will yield approximately this amount, if the samples are well preserved. If this is not the case, more sample material will be required.<\/p>\n<\/div>\n

Please fill out the\u00a0<\/span>sample submission form<\/a><\/strong>\u00a0<\/span>and provide the following additional information:<\/p>\n

    \n
  1. Brief (a few sentences) description of the project including overall objectives, reason for\u00a0<\/span>14<\/sup>C measurements, any relevant previous dating work, etc.<\/li>\n
  2. Brief description of sampling methodology and any pre-treatment already applied (eg, forams picked from marine sediments, sonicated in alcohol, etc).<\/li>\n
  3. Sample list: your lab number for each sample; a descriptive ID if is available (containing eg, stratigraphic information, species\/sample material, etc \u2013 core 58PC, 325 cm , bulloides); sample type (CO2<\/sub>, macrofossil, graphite, HPLC fraction, etc); measured or estimated carbon content; approximate expected age (eg bomb\u00a0<\/span>14<\/sup>C, modern, Holocene, ca. 40ka, etc).<\/li>\n
  4. Assessment of possible problems in interpretation, if applicable.<\/li>\n<\/ol>\n

    THE SUBMISSION FORM AND SAMPLE LIST SHOULD BE SENT VIA HARD COPY AND ELECTRONICALLY TO:<\/strong><\/p>\n<\/div>\n
