Fractionation and dating Bekanntschaften finden
If, however, all of the sample is converted completely from one form to another (eg.
solid to gas, acetylene to benzene) then no fractionation will occur.
Correction factors are available in most C14 texts.
A table showing isotopic fractionation of different substances in nature is shown here.
The ratio is measured using an ordinary mass spectrometer.
It is common practice in Carbon-14 laboratories to correct radiocarbon activities for sample fractionation.
The delta C13 value for a sample can yield important information regarding the environment from which the sample comes, because the isotope value of the sample reflects the isotopic composition of the immediate environment.
