Bases may be used to remove contaminating humic acids.

Some types of samples require more extensive pre-treatment than others, and these methods have evolved over the first 50 years of radiocarbon dating.

In contrast, methane made from petroleum products had no measurable radioactivity.the field deflects atoms of different masses differently (heavier atoms deflect less).Targets tuned to different atomic weights count the number of c12, c13, and c 14 atoms in a sample.This is the clock that permits levels of c14 in organic archaeological, geological, and paleontological samples to be converted into an estimate of time.The measurement of the rate of radioactive decay is known as its half-life, the time it takes for half of a sample to decay.
