The Keck-CCAMS facility was set up to expand UC and US capabilities for 14 C measurements in support of research into the carbon cycle and its links to climate. One of the aims was to minimize measurement cost by emphasizing large scale projects plus encouraging users to carry out sample processing at their own institutions.

Researchers from other fields or submitters with fewer than ten samples are encouraged to contact other AMS facilities or commercial dating services: Contact information for other laboratories can be found at the Radiocarbon journal web site, at radiocarbon dating lab california. Submitters, and in particular those making their first application, must make contact with the laboratory to discuss their requirements prior to actually submitting samples. See contacts for more info.

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 radiocarbon dating lab california. However, it is up to the submitter to define and select the materials to be dated: 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 14 C measurement is 1 dansk dating sites 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. For low-carbon organic material the carbon content can vary widely and no estimate for the preferred minimum sample size can be given. Note that smaller sample sizes can be dated at a reduced precision. For more details contact us. It is important to try to avoid storage and packing methodologies that may contaminate your sample.

Please follow the guidelines described below:. If possible, try to keep samples frozen or dry. We prefer to receive samples in small glass or plastic vials, or wrapped in aluminum foil. If you intend to send samples to us and there is any possibility that somebody could have used 14 C tracer in your facility even in the past contact us first. If necessary radiocarbon dating lab california will send you a monitoring kit for swiping your laboratory and suspect areas, to test for tracer contaminations.

This procedure is important for avoiding serious consequences radiocarbon dating lab california contamination of your samples and our laboratory. Check Swipe Protocol PDF file for more information. Also check the useful tips to avoid 14 C tracer epidemics PDF file. If samples require additional processing, the submitter will be informed of the added cost radiocarbon dating lab california work proceeds. Results are routinely corrected for isotopic fractionation using AMS-measured delta 13 C ratios, but precise IRMS delta 13 C measurements can be provided at additional cost.

Check price list for more information. All samples which must pass through U. Each shipment should contain a packing list of samples inside the main box, including the name and radiocarbon dating lab california of the shipper. In addition, the identification code of the sample, laboratory sample code when sample was previous treated outside our labtype of radiocarbon dating lab california and any other relevant information.

See our price list or contact us. Do not send any sample before contacting the Keck-CCAMS personnel. Please fill out the sample submission form and provide the following additional information:. Keck - CCAMS Group Earth System Science Department B Croul Hall University of California, Irvine Irvine, CA Submitters should arrange for a purchase order to be sent to the Keck-CCAMS contact. The account officer will then send an invoice when the results are completed.
