Step 1

Prepare recommended quantity

ASTM D7459 gas bag

Sampling CO2 gas directly from the emissions of a facility will provide the most accurate calculation of total renewable fuel used. You may submit as little as 2 cc of CO2 in a gas collection bag if the sample is not diluted. Please ensure that the gas bag is only 3/4 full and placed in a sturdy box. We also recommend that you take a duplicate sample in the event of a leakage.

For details on how to collect gas samples, see ASTM D7459.

The lab also accepts gas samples stored in vacutainers.

dewired and shredded tire

For tires, the best option to get a representative sample is to submit CO2 samples (collection guidelines under ASTM D7459). If not possible, what is important is that you take a cross section of the tire or the equivalent sample that represents the entire composition of the tire. Although 5 grams of tire is more than sufficient for an ASTM D6866 analysis, it might not be representative of the tire sample.

Note: Beta will NOT accept tire fragments for analysis. Samples submitted must be dewired and in shredded form.

Sampling – Unless otherwise instructed, we will subsample the submitted material in a quantity reasonable for the analytical method.

RDF Pellet

Unless otherwise instructed, we will subsample the submitted material in a quantity reasonable for the analytical method. If there are any special instructions to ensure the subsample best represents the client’s interests, please discuss with the laboratory prior to analysis. Since the laboratory cannot be experts in all manufacturing processes and products, the responsibility for analysis of a representative subsample lies with the client/submitter.

Step 2

Fill out all necessary documents

Shipments arranged through a freight forwarder must be sent under DDP terms. The shipper is responsible for handling the administrative requirements to release the shipment.


Analyses are started immediately upon receipt of samples to best ensure we meet our promised delivery. This means that charges are also incurred immediately upon receipt of samples. Change orders are welcome, but please be aware that partial or full charges will apply based on how much work has been completed by the time of the change request.

Beta Analytic publishes one report with a unique certificate number for each sample submitted.

We have no minimum number of samples required. If you are submitting samples for regulatory compliance or greenhouse gas emissions trading schemes, please consult the governing agencies regarding the testing frequency and the number of samples required for each collection period.

No. You can buy Tedlar gas bags from any supplier.

No, gas sampling is not part of Beta Analytic’s services.

A Beta representative will contact you to confirm the safe arrival of your samples in MIAMI and to quote you a delivery date for the results. Our quoted turnaround time starts following the day of receipt at the Miami laboratory excluding weekends.

Samples being delivered to the lab after 3 PM EST will be logged in the system the following day.
