We present a detailed abundance analysis of high-quality HARPS , UVES and UES spectra of 95 solar analogs , 33 with and 62 without detected planets .
These spectra have S/N > 350 .
We investigate the possibility that the possible presence of terrestrial planets could affect the volatile-to-refratory abundance ratios .

We do not see clear differences between stars with and without planets , either in the only seven solar twins or even when considering the whole sample of 95 solar analogs in the metallicity range -0.3 < \mathrm { [ Fe / H ] } < 0.5 .
We demonstrate that after removing the Galactic chemical evolution effects the possible differences between stars with and without planets in these samples practically disappear and the volatile-to-refractory abundance ratios are very similar to solar values .

We investigate the abundance ratios of volatile and refractory elements versus the condensation temperature of this sample of solar analogs , in particular , paying a special attention to those stars harbouring super-Earth-like planets .
