A method for the separation and direct detection of peroxynitrite (ONOO − ) and two of its degradation products, nitrite (NO 2− ) and nitrate (NO 3− ), using capillary electrophoresis with ultraviolet detection is described. The separation parameters were optimized and included electrokinetic injection, a run buffer consisting of 25mM K 2 HPO 4 7.5mM...
