  As an ongoing study of Magellanic Cloud PNe we have obtained UV spectra of 9
PNe in the SMC to measure their carbon abundances. The spectra have been
acquired with ACS HRC/PR200L and SBC/PR130L. The ACS prisms give a reasonable
resolution in the range of 1200 -- 2500 A to detect the C IV, C III], and C II]
nebular emission, essential for chemical studies of the PNe. The carbon
abundances of SMC PNe, together with those of the LMC previously determined
with STIS spectroscopy, will allow a comparative study of nebular enrichment
and provide the basis for comparison with stellar evolution models at various
metallicity.
