AbstractAn improved method has been developed to evaluate element abundances from emission line intensities of thin plasmas, depending on the differential emission measure (DEM) of the source. Observations made by the SERTS Rocket EUV Spectrograph are used to perform a detailed analysis of the DEM distribution for temperatures larger than 105K in a solar active region.Comparison of the DEM distributions obtained by means of lines from different elements allows the verification of relative abundances for the most common elements of the solar corona, and gives an abundance estimates for the minor components, such as Na, Al, Ar, Cr, Mn and Zn.
