This work presents an upper bound on the neutrino mass using the emission of νe from the neutronization burst of a core collapsing supernova at 10~kpc of distance and a progenitor star of 15~M_\odot. The calculations were done considering a 34 kton Liquid Argon Time Projection Chamber similar to the Far Detector proposal of the Long Baseline Neutrino Experiment (LBNE). We have performed a Monte Carlo simulation for the number of events integrated in 5~ms bins. Our results are mν<2.71~eV and 0.18~eV<mν<1.70~eV, at 95% C.L, assuming normal hierarchy and inverted hierarchy, respectively. We have analysed different configurations for the detector performance resulting in neutrino mass bound of O(1)~eV.
