Advantages to radiocarbon dating
The identical reaction is performed on reference standards, internal QA samples, and backgrounds to ensure systematic chemistry.
The analytical result (“BP” or “p MC”) is obtained by measuring sample C14/C13 relative to the C14/C13 in Oxalic Acid II (NIST-4990C) in one of Beta Analytic’s multiple in-house particle accelerators using SNICS ion source.
The company routinely delivers AMS radiocarbon dating results within 14 business days.
The AMS measurement is done on graphite produced by hydrogen reduction of the CO2 sample over a cobalt catalyst.
More researchers are using a mix of both AMS and radiometric dating in order to properly answer the complex questions posed by their research.
The AMS radiocarbon dates are systematically the same or consistent with any of the radiometric dating results provided by Beta Analytic since 1979.
In addition to reference standards, we circulate “blind” known-age samples, which were measured radiometrically at Beta Analytic to ensure non-biased results.
Also, we have an unprecedented quality control program (which we would be glad to send you a copy). We have many years experience in all aspects of radiocarbon dating; you’re very welcome to take advantage of this expertise.
Radiocarbon Dating Groundwater The application of radiocarbon dating to groundwater analysis can offer a technique to predict the over-pumping of the aquifer before it becomes contaminated or overexploited.
The CO2 is obtained from the combustion of the sample at 800°C under a 100% oxygen atmosphere.
The CO2 is first dried with methanol/dry ice then collected in liquid nitrogen for the subsequent graphitization reaction.
The AMS result is corrected for total fractionation using machine graphite d13C.
The d13C reported for the sample is obtained by different ways depending upon the sample material.
