At this stage, molecules that may be present are eliminated because they cannot exist in this triple charged state.
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.
At this stage, other negatively charged atoms are unstable and cannot reach the detector.
The negatively charged carbon atoms, however, move on to the stripper (a gas or a metal foil) where they lose the electrons and emerge as the triple, positively charged carbon atoms.
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.
