Through interpretation of these results, the origin and age of the gasoline can often be determined and, hence, responsibility for the release can may be identified. (2016) Forensic Characterization of Gasoline Releases Impacting the Environment. (eds) Soil in Criminal and Environmental Forensics. Precision Testing Labs (PTLabs), based in Toms River, Ocean County, NJ at 732-905-5000 is a full service environmental testing lab certified by the New Jersey Department of Environmental Protection (NJDEP), #15005. The consultant-laboratory relationship is paramount ... Aside from radiocarbon dating, ISO/IEC 17005-accredited Beta Analytic also provides biobased/renewable carbon content testing to manufacturers, product distributors, and researchers worldwide for biobased products, biofuels, waste-derived fuels and their combustion emissions (CO2 gas).The lab also uses Carbon-14 analysis for natural product source testing on materials such as flavors, fragrances, essential oils, cosmetics and supplements to identify petrochemicals.Beta Analytic uses Accelerator Mass Spectrometry (AMS) technology, which gives the most advanced precision and accuracy for Carbon-14 measurements.The lab is based in Miami, Florida, and is the world leader in Carbon-14 analyses since 1979.For example, new regulations imposed by the California Air Resource Board (CARB), reduced the most volatile hydrocarbon components of gasoline, especially benzene (which was decreased to ~0.5% of total gasoline weight), and lowered the sulfur content of diesel No. Leaded gasoline was first marketed in 1923, and until 1960 tetraethyl lead (TEL) was used as the only antiknock agent.
The AMS measurement is done on graphite produced by hydrogen reduction of the CO2 sample over a cobalt catalyst.Several approaches can be taken to determine the approximate time of a release.Composition of a fuel depends on when it was produced.The lab also offers C: N, %C and %N measurements on collagen extracted from non-cremated bones in addition to δ15N and δ13C at no additional cost for samples sent for radiocarbon dating.The lab also provides stable isotope analyses on a standalone basis.
