Fixed‐potential anodic detection of ammo acids and peptides can be carried out at ruthenium dioxide (RuO 2 ) ‐modified carbon paste and graphite epoxy electrodes. The effect of various experimental variables on the electrocatlytic response is explored. Optimal detection is obtained under strongly alkaline conditions and a low ( + 0.45 v vs. Ag/AgCl) operating potential. With flow injection, the response is fast, linear, and reproducible )relative standard deviations of 1.5 to 1.7%, n = 32). Similar advantages are reported for the incorporation of cobalt oxide (CO 3 O 4 ) into carbon paste detectors.
