What can radiocarbon dating date

AMS technology has allowed us to date very small samples (such as seeds) that were previously undatable.Since there are practical limits to the age range of the method, most samples must be younger than 50,000 years and older than 100 years.

The sample is converted to graphite and mounted in an ion source from which it is sputtered and accelerated through a magnetic field.For example, it was once standard practice to simply burn whole bones, but the results were eventually seen to be unreliable.Chemical methods for separating the organic (collagen) from the inorganic (apatite) components of bone created the opportunity to date both components and compare the results.Most samples require chemical pre-treatment to ensure their purity or to recover particular components of the material.The objective of pre-treatment is to ensure that the carbon being analyzed is native to the sample submitted for dating.

Since carbon is fundamental to life, occurring along with hydrogen in all organic compounds, the detection of such an isotope might form the basis for a method to establish the age of ancient materials.
