Resumen:
The mass composition of ultra-high energy cosmic rays is a critical
issue to understand their origin and nature. The Pierre Auger
Observatory is a hybrid instrument which provides a powerful environment
for the determination of the primary mass. The Surface Detector of the
Pierre Auger Observatory alone allows the study of several shower
parameters with high discriminating power between primary elements.
Novel analysis techniques using different features of signals in the
Cherenkov stations are discussed. These are the signal risetime, the
azimuthal time asymmetry and the muon density of the showers.
