  Using high-dispersion, high-quality spectra of HD 30085 obtained with the
echelle spectrograph SOPHIE at Observatoire de Haute Provence, we show that
this star contains strong lines of the s-process elements Sr II, Y II and Zr
II. Line syntheses of the lines yield large overabundances of Sr, Y, Zr which
are characteristic of HgMn stars. The Sr-Y-Zr triad of abundances is inverted
in HD 30085 compared to that in our solar system. The violation of the odd-even
rule suggests that physical processes such as radiative diffusion, chemical
fractionation and others must be at work in the atmosphere of HD 30085, and
that the atmosphere is stable enough to sustain them.
