We present examples of early, unreduced results obtained from the instrument package dedicated for spectroscopic studies of coronal flaring plasma composition. The package consists of two Bragg spectrometers, RESIK and Diogeness. These instruments have been launched aboard the Russian Coronas-F solar observatory on 31 July 2001. The data being received from these two spectrometers allow for determining the absolute abundances of several important elements including that of low and high first ionization potential (FIP). Based on the data which have been (and hopefully will be) obtained, we will investigate fast temporal variations ( ~ 1 min) of the plasma composition in flares and hotter active regions. The analysis of spectra obtained will certainly allow for spectroscopic studies of several, so-called ''triplet'' lines forming in He-like, highly ionized plasma since the spectra received are apparently of unprecedented quality.
