This work presents an upper bound on the neutrino mass using the emission of \(\nu_e\) 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 \(m_\nu<2.71\)~eV and \(0.18~\mbox{eV}<m_\nu<1.70\)~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 \(\mathcal{O}(1)\)~eV.
