dc.description.abstractA triple-potential waveform used for amperometric detection of streptomycin (STP) is investigated. The mobile phase is an aqueous solution of 75 mM phosphoric acid. Waveform parameters are optimized to maximize the signal-to-noise ratio (S/N). The potentials of the waveform are designated E1, E2, and E3, and potentials are maintained for time periods t1, t2, and t3. Unlike the normal triple-potential waveform, the cleaning function is accomplished at negative potential instead of positive potential in our triple-potential waveform. The detection limit of STP is < 0.04 μg mL -1 (S/N = 3). The linearity of STP ranges from 0.1 to 5 μg mL -1 (r = 0.9986). RSD (n = 30) of the peak area of STP is 5.8%. The triple-potential waveform shows low detection limits and long-term reproducibility. Copyright © Taylor & Francis, Inc.
