Away from Earth, argon-36 is the most abundant isotope, synthesized in the silicon burning phase of stars with a mass of about 11 or more Earth suns. During silicon burning, an alpha-particle adds to a silicon-32 nucleus to make sulfur-36, which can add another alpha-particle to become...
The addition of O2 to the outer plasma gas increases the electron number density [241] and the excitation temperature of the plasma [252,253], generally serving to enhance analyte intensities [237,254,255]. O2 has also been added to the central channel, mixed with the Ar nebulizer flow, ...
