The Accelerator Mass Spectrometry (AMS) technique for radiocarbon dating accounts for a substantial number of the analysis requests Beta Analytic receives each day.

There can be considerable advantages to using the AMS technique in many dating applications, making it possible to extend radiocarbon dating into many new areas of research.

This resemblance is used in chemical and biological research, in a technique called carbon labeling: carbon-14 atoms can be used to replace nonradioactive carbon, in order to trace chemical and biochemical reactions involving carbon atoms from any given organic compound.

These are relatively low energies; the maximum distance traveled is estimated to be 22 cm in air and 0.27 mm in body tissue.

The period of time that it takes for half of a sample to decay is called a "half-life." Radiocarbon oxidizes (that is, it combines with oxygen) and enters the biosphere through natural processes like breathing and eating.

The identical reaction is performed on reference standards, internal QA samples, and backgrounds to ensure systematic chemistry.

The analytical result (“BP” or “p MC”) ​i​s obtained by measuring sample C14/C13 relative to the C14/C13 in Oxalic Acid II (NIST-4990C) in one of the lab’s multiple in-house particle accelerators using SNICS ion source.
