In anticipation of the Gaia astrometric mission, a large sample ofspectroscopic binaries has been observed since 2010 with the SOPHIEspectrograph at the Haute--Provence Observatory. Our aim is to derive theorbital elements of double-lined spectroscopic binaries (SB2s) with an accuracysufficient to finally obtain the masses of the components with relative errorsas small as 1 % when the astrometric measurements of Gaia are taken intoaccount. In this paper we present the results from five years of observationsof 10 SB2 systems with periods ranging from 37 to 881 days. Using the TODMORalgorithm we computed radial velocities from the spectra, and then derived theorbital elements of these binary systems. The minimum masses of the componentsare then obtained with an accuracy better than 1.2 % for the ten binaries.Combining the radial velocities with existing interferometric measurements, wederived the masses of the primary and secondary components of HIP 87895 with anaccuracy of 0.98 % and 1.2 % respectively.
