The pricing schedule (Canadian Non-profit or Commercial) is assigned based on the billing address listed on the cover sheet of the submission form and the pricing posted on our website at the time of submission."Canadian Non-profit" is defined as Canadian academic institution, Canadian Government agency, Regsitered Canadian non-profit organization, or Canadian Indigenous Group.Bulk sediment can contain carbon from more than one reservoir and occasionally this can lead to a freshwater reservoir effect, such as in hardwater regions or lakes where old carbon is washed in from the catchment during spring melt or floods.Having said that, bulk sediment is widely used for radiocarbon dating, especially in cases when macrofossils are unavailable.For non-profit users, an invoice is issued upon delivery of the the results, and payment is required withing 30 days.
For bulk samples, some consultation may be needed to determine whether a simple acid wash, AAA method, or compound specific analysis is needed.
Please indicate on the submision form if you would like stable isotope measurements.
For teeth the dentine is most reliable for dating as the enamel exchanges carbon with the environment.
Avoid porous (cancellous tissue) or soft bones as these are aslo likely to be low in collagen.
For δ13C and δ15N, we submit the extracted collagen to our partner lab, the .
