The supernova remnant 1E0102.2-7219 has been observed with the High Energy Transmission Grating Spectrometer (HETGS) of the Chandra X-ray Observatory. Using the high resolution X-ray spectrum, we have measured the fluxes of individual emission lines of oxygen, neon, magnesium, and silicon. Little Fe is present. Using ISIS and XSPEC, we have fit plane parallel shock models and non-equilibrium (nei) models to ratios of the line flux measurements. In this poster we present our examination of the resulting plasma diagnostics, exploring their sensitivity to parameters like column density, electron-ion equipartition, and two ionization timescales. No single model fits all global measurements. We also discuss the implications for this SNR. This work was prepared under NASA contract NAS8-38249 and SAO SV1-61010.
