We reprocess the Hipparcos Intermediate Astrometric Data of know spectroscopic binaries (retrived from the 9th catalogue of spectroscopic binary orbits, http://sb9.astro.ulb.ac.be) to see whether the orbital inclination, and thus the mass of the secondary, can be derived. Several statistical tests (Pourbaix & Arenou 2001) are used to ensure the reliability of the fit. About 70 systems (originally processed as single stars) out of 863 benefit from the orbital model.
