Advantages and disadvantages of radiocarbon dating

This may cause some of the sample's molecules to break into charged fragments.These ions are then separated according to their mass-to-charge ratio, typically by accelerating them and subjecting them to an electric or magnetic field: ions of the same mass-to-charge ratio will undergo the same amount of deflection.

Once the instrument was properly adjusted, a photographic plate was inserted and exposed.

The term mass spectroscope continued to be used even though the direct illumination of a phosphor screen was replaced by indirect measurements with an oscilloscope. Sector mass spectrometers known as calutrons were developed by Ernest O.

(Other analyzer types are treated below.) Consider a sample of sodium chloride (table salt).

In the ion source, the sample is vaporized (turned into gas) and ionized (transformed into electrically charged particles) into sodium (Na) ions.

The magnitude of the deflection of the moving ion's trajectory depends on its mass-to-charge ratio.
