在这份报纸，四倍潜力的波形被颠倒的阶段离子对层析为 gentamicin 的决心调查并且优化。而不是一个相对高的积极潜力，一个否定潜力为清洗金工作电极作为一个潜力被采用。由这样，在清洗的 analyte 察觉和电极期间源于高积极的潜力的应用程序的金氧化物的形成极大地被减少，并且因此，金工作电极的溶解和衰退也被减少。工作电极由这四倍潜力的波形完成了的黄金的好条件能帮助我们获得好重制度。以便尽可能高获得 signal-to-noise 比率，影响 gentamicin 的察觉的几个波形参数小心地被选择。分析方法与低相对标准差被用于二件真实 gentamicin 样品，和好结果的决心不超过 4% 被获得。

英文摘要：

In this paper, a quadruple-potential waveform was investigated and optimized for the determination of gentamicin by reversed phase ion-pair chromatography. Instead of a relatively high positive potential, a negative potential was adopted as a potential for the cleaning of gold working electrode. By this way, the formation of gold oxide resulting from the application of high positive potential during the analyte detection and electrode cleaning was greatly reduced, and therefore, the dissolution and recession of gold working electrode was also reduced. The good condition of gold working electrode achieved by this quadruple-potential waveform can help us to obtain a good reproducibility. In order to acquire signal-to-noise ratio as high as possible, several waveform parameters affecting the detection of gentamicin were carefully selected. The analytical method has been applied to the determination of two real gentamicin samples, and good results with low relative standard deviation not more than 4% were obtained.
