In mass analysis, a magnetic field is applied to these moving charged particles, which causes the particles to deflect from the path they are traveling.
If the charged particles have the same velocity but different masses, as in the case of the carbon isotopes, the heavier particles are deflected least.
At this stage, molecules that may be present are eliminated because they cannot exist in this triple charged state.
The carbon atoms with triple positive charge further accelerate away from the positive terminal and pass through another set of focusing devices where mass analysis occurs.
These two radiocarbon dating methods use modern standards such as oxalic acid and other reference materials.
Although both radiocarbon dating methods produce high-quality results, they are fundamentally different in principle.
Reference materials are also pressed on metal discs.
These metal discs are then mounted on a target wheel so they can be analyzed in sequence.
Radiometric dating methods detect beta particles from the decay of carbon 14 atoms while accelerator mass spectrometers count the number of carbon 14 atoms present in the sample.
Both carbon dating methods have advantages and disadvantages.
From these data, concentration ratio of the isotopes can be known to allow evaluation of the level of fractionation.
