Sample Submission Step-by-Step

Sample Submission Step-by-Step

1. Sampling Preparation

1.1 Understand the vendor approval obligations of your institution and if necessary receive approval, via purchase order or similar. 


1.2 See our Sample Type sections for sample selection and submission recommendations:

2. Submission Form

2.1 Submitter Information: 

  • Name, Date, Institution (or private), Address, Phone, Email

2.2 Invoicing Information: 

  • Name, Purchase Order or Project Number, Institution, Address, Phone, Email

2.3 Requested Services & Fee Estimate: 

  • Mark the quantity (number of samples) submitted for each sample type according to the desired turn-around time. Standard Service is 4-6 weeks while Express is 15 business day for Bone and 10 business day for all other radiocarbon services. 

         Note if you would like your samples returned, and if you have any additional data report or invoicing requests.

2.4 Sample List:

  • Provide Sample IDs corresponding to the labeled samples, what the material type is, site or location, feature, stratigraphy, or description of the environmental context, depth, and expected age. 

    • Contextual information about the sample is vital to applying the most appropriate chemical pretreatment for removing suspected contaminants.

  • If you are submitting pretreated material, please provide a summary of the pretreatment protocol.

2.5 Notify us in advance if you are submitting more than 30 samples; you are welcome to provide the digital version of your completed Submission Form or a spreadsheet version of the submission list. 

3. Submission Preparation

3.1 Samples:

  • Wrap most samples directly in aluminum foil. This will minimize carbon contamination, cushion against sharp edges, and reduce static.

  • Place foil sample packet in a flexible secondary container, such as a plastic bag (e.g., Ziploc or Whirl-Pak). 

  • Label each bag individually with your unique sample ID.

3.2 Packages:

  • Package submissions in a rigid shipping container, such as a box or an envelope with additional padding.

    • Cushion containers for shipment in packaging material, such as additional plastic bags, bubble wrap, brown paper, or packing peanuts.

  • Include a completed hard copy of the DirectAMS Submission Form with the shipment.

  • We recommend using a courier that provides tracking services, such as USPSFedExUPS, or DHL.


3.3 Shipping Address:

Jacob Laugeson
11822 North Creek Parkway North
Suite 107
Bothell, WA 98011
Tel: +1.425.481.8122

  • Be sure to write the complete street name, including both instances of "North", and the suite number. Failing to do so could result in a lost or misdelivered package.

  • Providing a contact name is not required, but assists in lost or misdelivered package retrieval.
