This paper presents high resolution spectroscopy of the HX Vel (IDS 08390-4744 AB) multiple system. New spectroscopic observations of the system were made at Mt. John University Observatory in 2007 and 2008. Radial velocities of both components of HX Vel A were measured using gaussian fitting. The spectroscopic mass ratio of the close binary was determined as 0.599±0.052, according to a Keplerian orbital solution. The resulting orbital elements are a1sini=0.0098±0.0003 AU, a2sini=0.0164±0.0003 AU, M1sin3i=1.19±0.07 M⊙ and M2sin3i=0.71±0.04 M⊙.
