Step 1

Prepare the recommended quantity of sample material

ASTM D7459 gas bag

Gas Samples

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 absorbent cartridges and vacutainers.

Solid Samples:

For RDF, SRF, tires, waste, and sludge, send at least 5 grams (25 grams maximum) of material representative of the particular fuel being analyzed.

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.


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
