We study different method to discriminate hadronic composition with inclined showers. First of all, we looks at the ratio of positive and negative muons from different primaries and we also study the pattern that the secondary particles display at ground. We search if this pattern is different from proton and iron primaries and we focus on the two lobes that the muons picture at ground.We analyze for proton and iron primaries the mean in X and Y position of the positive and negative muons at ground and also their sigma, skewnes and the kurtosis. We conclude that these methods can not be apply to Auger data because the signal produced by the different primaries differ inside the error of the detector.
