An analysis of differential emission measure distributions (DEM) is one of the scientific goals of SphinX instrument. I will present the DEM distributions for a set of flares belonging to different GOES classes from the range B5.6 - X1. As the input data we have used absolute fluxes observed by RESIK in several spectral bands (lines+continuum). Respective emission functions have been calculated using the CHIANTI v. 5.2 atomic data package. The DEM distributions have been calculated using 'Withbroe - Sylwester' multiplicative, maximum likelihood iterative algorithm. The skills gathered will allow to perform the DEM calculations based on the SphinX data.
