E0102-72 is the second brightest SNR in the Small Magallanic Cloud and has been observed for 140 ksec with the High Energy Transmission Gratings (HETG) aboard the Chandra X-ray Observatory. The small angular size and high surface brightness make this an excellent target for HETG and we resolve the remnant into individual lines. We observe fluxes from several lines which include, O VIII Ly-alpha, Ly-beta,and Ly-delta along with several lines from Ne IX and Mg XII. The ratios of these lines provide powerful constraints on the electron temperature and the ionization age of the remnant.
