  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< [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.
