FAQ: Natural vs Synthetic Testing by Carbon-14 Analysis

How is Carbon-14 analysis different from other test methods used to detect adulteration?

Only Carbon-14 analysis can verify if the adulteration is due to fossil sources (synthetic) whereas the other methods can only detect naturally sourced adulterants. To distinguish between different natural adulterants, other chemical analyses are needed, e.g. stable isotope analysis. Authenticity Testing Methods

What are your sample size requirements?

For liquids, please send 0.2 to 1 fl oz (0.5cc to 30cc). For solids, please send 0.1 to 1 oz (2.8 to 25 grams). Note: We can only receive chemicals and solvents in very small quantities – not exceeding 0.3 cc (300 microliters).

What containers should we use for sending samples?

We accept retail containers. For subsamples, our recommended container for liquids are 1-mL glass micro-sample vials with crimp tops that have a Teflon-lined septum. For more details on subsample containers and packing materials, please refer to our submission guidelines.

How many samples do we need to send?

Beta Analytic has no minimum number of samples required. We provide one report with a unique certificate number for each sample.

For research and development, one measurement is fine. If you are submitting samples for certification or regulatory compliance, please consult the governing agencies regarding their required number of test samples before submission.

Where should we send the samples?

Testing is done in our ISO 17025-accredited laboratory in Miami, Florida, but you may send samples to our other forwarding facilities if they are NOT designated as hazardous by the International Air Transport Association (IATA).

If you are in Europe, please send your samples to our Madrid office. For China, please send samples to our Xiamen address. For Japan, send the samples to our agent in Nagoya.

Do natural source test results show the actual ingredients in the product?

No. Test results only show the percentage of ingredients that come from biomass (e.g. plants, animals) versus components that are from fossil sources (e.g. petroleum-derived). Carbon-14 testing results do not provide any data regarding product formulation or individual ingredients.
