The resolving power, or Josef Mattauch, in Germany, independently developed instruments with electric and magnetic fields arranged in tandem in such a way that ion beams that emerged from the source slits in divergent directions and with different velocities were refocused. Smythe first proposed such a device in 1926 based on electrodes to which radio-frequency voltages are applied and which are arranged so that ions of a given velocity pass undeflected.

This spectrometer was employed by Dempster to make accurate determinations of the abundances of the isotopes of magnesium, lithium, potassium, calcium, and zinc, laying the foundation for similar measurements of the isotopes of all the elements.The most noteworthy observation made with the parabola spectrography was the spectrum of rare gases present in the atmosphere.In addition to lines due to helium (mass 4), neon (mass 20), and argon (mass 40), there was a line corresponding to an ion of mass 22 that could not be attributed to any known gas.Mass spectroscopes consist of five basic parts: a high vacuum system; a sample handling system, through which the sample to be investigated can be introduced; an ion source, in which a beam of charged particles characteristic of the sample can be produced; an analyzer, in which the beam can be separated into its components; and a detector or receiver by means of which the separated ion beams can be observed or collected.Many investigations have been conducted with the help of mass spectrometry.
