We present a spectroscopic analysis of the HgMn single-lined binary system HD 49022 belonging to the open cluster NGC 2287. The observations have been carried out at the Complejo Astronómico El Leoncito (CASLEO) with the Echelle REOSC sepctrograph. We identify spectral lines, determine the spectroscopic orbit, and estimate the physical parameters of the star, assuming cluster membership.
