Sample Submission

Sample accounting records

We prefer sample sets that are simply numbered sequentially — 1, 2, 3 … — with the client keeping a key that translates these numbers into more complete coding schemes. Please include our sample submission form by email or with your shipment stating that the shipment should contain n samples and any additional details under the “Sample IDs” column.

If you would like us to use more complex sample codes in our data report, please include with your sample shipment an itemized list of the sample codes and email an Excel or space-delimited text version to


It is our policy to re-analyze, at no cost to client, any samples lost to machine or analyst error. Samples submitted that are unable to be properly analyzed or that provide spurious results due to a) higher or lower than limits of detection b) matrix issues or c) improper preprocessing, prior to submission, will be subject to full analytical charges upon resubmission. If you, the client, have any doubt as to the concentration of your samples please contact us for advice. We will analyze, at no cost, 12 or fewer test samples to help ascertain best weight ranges prior to full sample set submission. For examples of ideal weights see:

Purchase Orders

In general we don’t need to see an actual copy of your institution’s purchase order before beginning your work, but will be content if you state in your sample shipment cover letter that the P.O. exists and is number such-and-such.

Please mention in your cover letter if you want your samples returned to you, and how they should be shipped.

If you request return of samples but don’t specify a method of shipping they will return to you via U.P.S ground C.O.D.
