Conferencia; 33rd International Cosmic Ray Conference; 2013

In this paper we outline the details of a method used to estimate the mass composition of ultra-highenergy cosmic rays, which is based on interpretation of the data on shower maximum, Xmax, measured using thefluorescence telescopes of the Pierre Auger Observatory. The analysis is performed using a variety of hadronicinteraction models. The results of our analyses will be presented at the Conference.
