Materials NOT SUITABLE for garbage disposal – Please contact the lab for discussion prior to submittal.
Multi-component Samples (e.g. toys, toothbrush, diapers, sanitary pads) – Please contact us before sending your samples. The lab will need instructions on which component to analyze especially for products with multi-color parts.
IMPORTANT: Beta Analytic can only receive chemicals, solvents, and fuels in very small quantities – not exceeding 0.3 cc (300 microliters).
We have no minimum number of samples required but note:
Recommended Container for Liquids – 1 mL glass micro-sample vial with a crimp top that has a Teflon-lined septum. The vial should only be ¼ – ½ full.
Please use plastic or glass vials as sample containers. Make sure the vials have snap caps or any tight closure that will prevent leakage. You can also use vials found at this site. Wrap the vials properly to prevent breakage during shipment.
Please make sure the vials have chemically non-reactive seals, e.g. made of a silicone disk with one or two teflon faces. If you use low-volume screw top vials like the amber one above, make sure they have a non-reactive cap liner made from silicone and teflon or some other chemically non-reactive material. Do not use vials that have caps lined with a piece of cardboard with an Aluminum-foil face on one side. The cardboard side is glued to the cap. These are not suitable for volatile liquids as the vapors can dissolve the glue and contaminate the sample during shipment.
Beta Analytic is a tracer-free laboratory. Samples that have been artificially enhanced with Carbon-12, Carbon-13, Carbon-14 or any other isotope cannot be accepted for analysis as they may cause damage to the lab’s equipment. Any damages to equipment or loss of equipment time resulting from samples that contain elevated isotope ratios will be the responsibility of the client and will be billed to the client.
It is the submitter’s sole responsibility to provide the laboratory with this information prior to analysis:
1. Presence of volatile components in the samples that may be lost during handling
Accurate analysis requires recovery of all available carbon within the product. If a biobased component is volatile and a petroleum component is not, the measured biobased content for the product will be too low if the volatiles are not recovered in the same proportion as the non-volatile petroleum components. Special procedures are readily applied to handle such samples but the laboratory needs to be aware of the need, e.g. evaporative hand sanitizers. Note that it is the submitter’s sole responsibility to provide the laboratory with this information.
2. Presence of any carbonates in the material to be analyzed
ASTM D6866 requires carbonate components to be excluded from the biobased content result. Special procedures are required for materials containing carbonates. The lab needs to know if there are carbonates within your product and discussion must be pursued prior to analysis to ensure accurate results.
3. Heterogeneity issues
For the analysis to be meaningful, the carbon analyzed must be representative of the whole product. The result itself only applies to the analyzed materials. Heterogenous materials should be discussed with the laboratory prior to analysis to ensure the analyzed material is representative of the whole product.
4. Presence of carcinogenic materials
Our laboratory does not have the facilities for handling or disposing certain hazardous materials, and as such we cannot accept carcinogenic materials or materials requiring special disposal procedures. In the case of highly flammable or certain toxic materials (e.g. phenols), we can accept very small quantities such that disposal is not an issue. However, please contact us prior to sending the samples to discuss on the appropriate amount to send.
