Abstract
We present an analysis of the physical and chemical conditions of the planetary nebulae NGC 6302 and NGC 2440 through spatially resolved spectroscopy. Long slit spectrophotometric data were obtained with the Goodman spectrograph attached to the 4.1 m SOAR telescope in several different declinations with the slit on the East-West direction. From them, maps and spatial profiles were constructed. Electron densities were calculated from the [S II] and [Ar IV] sensors, and electron temperatures from the [N II] and [O III] sensors. Small temperature fluctuations on the plane of the sky were obtained. Abundances of N^{+}, O^{+}, S^{+}, S^{2+}, O^{2+}, Ne^{2+}, Ar^{3+}, Ar^{4+} relative to H^{+} were determined from collisionally excited lines, and relative abundances of He^{+} and He^{2+} from recombination lines.
