Inductively coupled plasma mass spectrometry argon ions. Making the plasma from argon, instead of other gases, has several advantages. First, argon is abundant (in the atmosphere, as a result of the radioactive decay of potassium) and therefore cheaper than other noble gases. Argon also has a higher first ionization potential than all other elements except He, F, and Ne. Because of this high ionization energy, the reaction (Ar + e → Ar) is more energetically favorable than the reaction (M + e → M). This ensures that the sample remains ionized (as M) so that the mass spectrometer can detect it. Argon can be purchased
The More Abundant Life The More Abundant Life The More Abundant Life was a phrase of scriptural flavor used by the U.S. President Franklin D. Roosevelt in his address before the Inter-American Conference for the Maintenance of Peace in Buenos Aires, Argentina, December 1, 1936, to signify the improved living conditions and enlarged cultural and economic opportunities available to the whole world through the maintenance in the Western Hemisphere of constitutional representative government based on faith in God. The phrase is taken from the saying of Jesus at John 10:10: "The thief cometh not, but for to steal, and to kill, and to destroy:
