自1960年始,YSI商品化的复膜Clark电极就用于测定溶解氧,YSI极谱法测量成为工业标准并为实验室和广大部门所应用。存在的问题是这种方法在使用时,需要不停地摇动样品,使氧分子在通过膜扩散到阴极时已耗尽。为防止信号减小需要补充氧,这样在测样操作时需要不停地搅动。为解决长时期依靠搅动调节的问题,经过多年的研究,YSI公司发明了快速脉冲系统,大大减少了溶解氧测量时对搅动的 Since the 1960’s, YSI’s commercial Fresnel Clark electrodes have been used to determine dissolved oxygen. YSI polarographic measurements have become the industry standard and are being used by laboratories and a wide range of industries. The problem is that when this method is in use, it is necessary to constantly shake the sample so that oxygen molecules are exhausted as they diffuse through the membrane to the cathode. In order to prevent signal reduction need to add oxygen, so in the sample operation need to constantly stirring. In order to solve the long-term problem of relying on the agitation regulation, after years of research, YSI invented the fast pulse system, greatly reducing the dissolved oxygen measurement of the agitation
