半微分电分析描述了六氰高铁酸盐（III），重铬酸盐，铜（II），对氨基苯酚，对苯醌，间二硝基苯，鸟嘌呤，鸟苷，腺嘌呤和腺苷在固定固体工作电极。所有样品的电极过程都得到了近乎对称的尖峰曲线。通过实验证实了玻碳圆盘电极的峰高和峰电位与浓度、电极面积和电位扫描率的相关性。结果表明，固体工作电极技术比普通线性扫描伏安法具有更高的灵敏度和更好的分辨率。灵敏度略低于差分脉冲伏安法，但具有速度快的优点。
Semidifferential electroanalysis is described for hexacyanoferrate(III), dichromate, copper(II),p-aminophenol,p-benzoquinone,m-dinitrobenzene, guanine, guanosine, adenine, and adenosine at a stationary solid working electrode. Nearly symmetrical, peaked curves are obtained for the electrode processes of all the samples investigated. The predicted dependence of peak height and peak potential on concentration, electrode area, and potential scan rate are confirmed-experimentally for the glassy carbon disk electrode. It is demonstrated that the technique with the solid working electrode provides higher sensitivity and better resolution than ordinary linear sweep voltammetry. The sensitivity is somewhat worse than in differential pulse voltammetry, but the technique has the advantage of Speed.
