Online Form Features:
– Filling out multiple data sheets is now easier. You can duplicate any of the forms you’ve added and just fill out a new sample code and edit other fields like the weight.
– You can edit or delete a data sheet before sending the other forms to the lab.
– You only need to add your contact details and payment information once.
– You can review the data sheets before submission. The forms are sent to the lab only after you click on “Submit.”
* Sample Code – Please provide your internal reference code for each sample. This is an identification code unique to each material submitted as indicated on the sample container. This code will appear on the final report. Please limit to 12 characters (max).
* Material Type – If material is not listed, select “Other” and write the material type on the given blank space.
Weight – Please provide the sample’s weight and choose a corresponding unit of measure found in the dropdown menu. Choices are mg, g, mL, and L.
Contamination – Note the evidence of contamination, e.g. root penetration, leaching, humic acids, etc.
Stratigraphic and Environmental Details – Add a general description of the location where the sample was taken.
* General Geographic Location – Note the geographic location where the sample was taken.
Standard (14 business days or less turnaround time)
Priority (6 business days or less turnaround time)
Time Guide (2-3 business days or less turnaround time)
NOTE: Some additional days might be necessary for difficult bone samples
Not applicable to bones, sediment, phytolith, pollen, forams, teeth, fish otoliths, or water. Results are reported in 30 business days. The lab needs 3-4 grams of actual carbon after pretreatment.
Solvent Extraction – Applicable to samples submitted for AMS dating that are contaminated with varnishes, preservatives, oils, tar, etc.
Solvent Extraction is useful for samples of carbonized or non-carbonized wood, plant and/or bone that have been exposed to fossil hydrocarbons in the ground or during archival storage (such as from fumigants / insecticides) and when some consolidants and preservatives have been used.
Cellulose Extraction – Applicable to nonburned wood and museum samples contaminated with fumigants, preservatives, or significant handling.
Cellulose Extraction is useful for samples of non-carbonized wood and plant that may have been exposed to high levels of contamination from natural or anthropogenic sources which may not be removed with standard acid/alkali/acid pretreatment. This may include contamination by insect or boring organisms, some types of applied preservatives. NOTE: Cellulose Extraction is recommended for best results when doing tree-ring studies to ensure the removal of natural organic resins which may migrate through the tree.
Collagen Extraction – Conventional method, applicable only to non-cremated bones
Ultrafiltration – Applicable only to non-cremated bones
Carbonate Extraction – Bone Carbonate Extraction is used for dating bones that have been fully cremated (heated above 600°C for sufficient time to form large, well-structured crystals of structural carbonate which are primary to an individual’s diet). Cremated bones will be void of collagen, white in color, and show no blue, black or gray coloration on the surfaces or interior of the bone when broken into two. Cremated bone fragments may be significantly less dense than normal bone.
δ13C – Included with all C14 measurements. Available NOT in conjunction with C14 (extra fees apply).
δ15N – Recommended for bones for dietary isotopic analysis. Free for non-cremated bones sent for C14 dating. Also available NOT in conjunction with C14. Fees vary accordingly.
δ18O – Free for water and carbonates sent for C14 dating depending on sample size. Also available NOT in conjunction with C14. Fees vary accordingly.
δD – Free for water sent for C14 dating. Also available NOT in conjunction with C14. Fees vary accordingly.
C:N – Free for non-cremated bones sent for C14 dating. Also available NOT in conjunction with C14. Fees vary accordingly.
Delta-R Value – For marine carbonate samples only
Please visit www.radiocarbon.com/m to get the Delta±R value for the general geographical region of your site and email the value to the lab together with the DeltaRErr value – without this number the Delta-R value is invalid. Note: A negative Delta-R will make the date older (typically presuming freshwater dilution from the global marine average)
When on the site, you can zoom in closer using the bar on the left of the screen. You can right-click and drag to center the map on your location. When your area is centered and zoomed in to a few hundred miles, please left-click on your sample location and a green point should show up. Click GET DATA. A table with the 10 closest known points will appear. You can check off just one value from the table or check off several in the table. Please look at the distances these spots are from your site. Some points may be quite far from your site and not relevant. Unfortunately we cannot tell you how close a value should be to be relevant to your area. You can now click on CALCULATE AVERAGE OF TICKED BOXES. If there are no points close to your site, let us know and we will NOT use a local correction but will still use the global marine correction.
You can edit the data sheets before submitting them to the lab.
Client Information – Put the submitter’s contact information here. The contact listed here will receive the results.
Payment information – If payment will be processed by another person, please fill out the contact section. If paid by the submitter, please tick the “Same as Client” box. Our payment terms are found here.
Sample Size Requirements – Please refer to our website for the lab’s required sample sizes. www.radiocarbon.com/samplesizes
Sample Container – Place large samples directly into Ziplock bags. Small samples or those with fine particles should be wrapped in aluminum foil to contain them in a pouch before placing them in a labeled Ziplock bag. For groundwater samples, please put the bottles inside a plastic bag and seal the bag with a zip-tie or duct tape. If any of the bottles leak during shipment, the water will not weaken the cardboard shipping container.
We highly recommend sending your samples in small boxes whenever possible (instead of using envelopes) to protect the physical integrity of the samples during shipment. The equipment used by postal services typically run envelopes through rollers during the automated sorting process, and the small amount of pressure exerted during this process is enough to crush small fragments and powder them.
Shipping – Please refer to our website for our shipping addresses and recommended customs declaration. www.radiocarbon.com/shipping. We highly recommend that you send your packages with a tracking number. Please email the courier service name and tracking number so we can monitor your package.
