For more than two decades, the CAIS has developed and applied methods and analytical techniques for the field of biobased product determination and biofuel content. Biobased products are those derived from renewable resources such as sugar cane, coconut, corn and other biogenic materials rather than from fossil-fuels such as petroleum, coal or natural gas. These commercial or industrial products, unlike those tested under the Center’s food and flavor authenticity program, are not used for food and feed.
For samples submitted for the USDA Biopreferred program, we also need the Sample Selection or Vendor form with the USDA application number – this form is completed through the Biopreferred website. Once we receive approval from USDA, we can commence with testing your sample(s). If not for the USDA Biopreferred program, labeled samples can be sent directly to the address on the Center’s biobased submission form. Unlabeled samples cannot be processed. Send at least 10 grams or a representative labeled sample to “Biobase Testing Lab” at the address below. For information about the USDA Biopreferred Certification Program check here.
The CAIS offers the most current ASTM D6866 Method B using Accelerator Mass Spectrometry (AMS) with stable isotope correction. Method C using liquid scintillation counting (LSC) is no longer available. The CAIS continues its development of biobased product research and is instrumental in the continuance of the ASTM D6866 method as an active member of the Technical Advisory Committee of the USDA BioPreferred Program.
Biobased samples containing any amount of inorganic carbonate (such as sodium bicarbonate) or more than 50% water should be identified as such and will have an additional processing fee of $50 each. We also charge a $20 reporting fee for USDA Biopreferred samples. Contact the Biobased Product Testing Facility for more information.
Prepayment is not required – we will invoice you when the testing is complete. Payment options are described here. If you would like a formal quote, please fill out our submission form indicating billing contact information, requested turnaround time, number of samples and if any of the above fees are applicable to your samples.

Biobased Product Testing Submission Form
The Center for Applied Isotope Studies is and always has been a tracer-free facility: we do not accept, handle, graphitize or count samples containing Tracer or Labeled (Hot) 14C due to the risk of cross-contamination.
