We have done a spectroscopical analysis of the type I planetary nebula (PN)NGC 5315, through high-resolution (R$\sim$40000) optical spectroscopy with UVESat the 8.2m Very Large Telescope, and medium-resolution (R$\sim$4800) near-IRspectroscopy with FIRE at the 6.5m Magellan Baade telescope, covering a widespectral range from 0.31 $\mu$m to 2.50 $\mu$m. The main aim of this work is toinvestigate the slow neutron(n)-capture process (the s-process) in theAsymptotic Giant Branch (AGB) star progenitor of a type I PNe. We detected andidentified about 700 features, including lines from the n-capture elements Kr,Se, and possibly Br and Xe. We compute physical conditions using line ratios ofcommon ions. Ionic abundances are computed for the species with availableatomic data. We calculate total abundances using recent ionization correctionfactors (ICFs) or by summing ionic abundances. Our results for common elementsare in good agreement with previous works on the same object. We do not find asubstantial s-process enrichment in NGC 5315, which is typical for type I PNe.
