The special strength of AMS among the mass spectrometric methods is its power to separate a rare isotope from an abundant neighboring mass ("abundance sensitivity", e.g. The pre-accelerated ions are usually separated by a first mass spectrometer of sector-field type and enter an electrostatic "tandem accelerator".

This is a large nuclear particle accelerator based on the principle of a Tandem van de Graaff Accelerator operating at 0.2 to many million volts with two stages operating in tandem to accelerate the particles.

At present, too few measurements of 14C in the atmosphere exist to explicitly test the model prediction shown in the figure left.

Additionally, the impact strips off several of the ion's electrons, converting it into a positively charged ion.The analyses are based on Accelerator Mass Spectrometry (AMS).
