Optimized separation of DA and NE with a mixed surfactant system i) 100 µM DA/NE mixtures were prepared in K+ stimulant ii) Samples were prepared exactly as in i) with no addition of analytes. A) Buffer = 25 mM TES, 25 mM SDS, 0.5 mM Tween® (pH=7.4) using a Pt detection electrode B) Same parameters as A), but using a carbon fiber detection electrode
