If necessary we 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 involving contamination of your samples and our laboratory.
Charcoal samples should be picked out, floated, or sieved from any accompanying sediment.
Prior to shipping, please dry charcoal samples for 12-24 hours at temperatures not greater than 70°C.
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’s 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.
In addition, the identification code of the sample, laboratory sample code (when sample was previous treated outside our lab), type of material and any other relevant information. Please contact us for any question or further details.
Our prices for sample preparation and AMS measurement vary depend on the submitter (UC /non-UC), sample material, pretreatment required, etc.
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 C tracer in your facility (even in the past) contact us first.
Please visually inspect your samples and remove any rootlets or other signs of physical contamination.
