Scope

This document specifies a method for determining the biobased content of liquid
petroleum products by radiocarbon analysis using accelerator mass spectrometry.
This document applies to organic liquid petroleum products containing carbon-based
components that produce carbon dioxide (CO2) gas when burned in the presence of
oxygen.
Caution. This document is intended for use in laboratories that are not exposed to
artificial 14C. Artificial 14C is commonly used in biomedical research in accelerator
mass spectrometry (AMS) laboratories, where biobased materials can be present
at concentrations exceeding 1000 or 100% and 100000 times greater than 1%
biobased material. Artificial 14C can be ubiquitous on laboratory door handles,
pens, desks, other surfaces, potentially contaminating samples and producing
falsely high biobased content results. Isolation has been shown to be the only
effective method to prevent contamination. Laboratories exposed to artificial 14C
require a completely independent chemistry laboratory and rigorous testing and
validation procedures. Acceptable conditions include the following.
a) Disclosure to clients that the laboratory whose samples are being tested also
handles 14C;
b) The chemistry laboratories handling 14C and testing biobased carbon
samples are located in different buildings;
c) Separate testing personnel and no access to each other's buildings;
d) No shared common areas such as lunchrooms and offices;
e) No sharing of supplies or chemicals;
f) Quasi-simultaneous quality assurance measurements are performed on the
detectors to ensure that the detectors themselves are not contaminated.
