SuperTIGER (Trans-Iron Galactic Element Recorder) is a large-area balloon-borne instrument built to measure the galactic cosmic-ray abundances of elements from Z=10 (Ne) through Z=56 (Ba) at energies from 0.8 to ~10 GeV/nuc. SuperTIGER successfully flew around Antarctica for a record-breaking 55 days, from December 8, 2012 to February 1, 2013. In this paper, we present results of an analysis of the data taken during the flight for elements from Z=10 (Ne) to Z=28 (Ni). We report excellent charge separation throughout this range, with an Fe charge resolution of 0.16 charge units. Using a small sample of our data (~1/40th of our total), we will compare our galactic element secondary to primary ratios (e.g. (Sc+Ti+V)/Fe) with those from other instruments operating at different energy ranges.
