Relationship between Q and solar gases

Given that more than 99% of the mass in the solar system is contained in the Sun and that the Sun, in contrast to the rocky material that constitutes the meteorites, has retained its full complement of volatile elements, it is clear that the Sun is the primary reservoir of 

So mass may be an important factor, but overall the situation is likely to be more complex. For example, ionization efficiency could also have played a role, given (a) the evidence in several cases for ion implantation as the process by which noble gases were introduced into their host phases (e.g., SiC, diamond section Origins and History), and 

Jovian atmosphere (Owen et al. 2001) and inferences from recent measurements on lunar soil grains (Hashizume et al. 2000) give the true protosolar nitrogen isotopic ratio— the majority of the nanodiamonds may be of local origin, and with it the P3 noble gases. 

the differences being mainly in the overabundances relative to solar at Kr (higher
