厦门大学化学系与厦门第二分析仪器厂试制成功75-3A型汞膜电极快速极谱仪。该仪器应用集成电路装置。仪器包括线性扫描电路、电极系统和记录电流部分。用两只运算放大器作为线性扫描电路和电流放大器。铂球镀银沾汞的汞膜电极代替滴汞电极作常规极谱分析,也可用为溶出分析。用此种电极和仪器在有关单位按常规极谱分析已用于铜合金中的铅和锌,矿物中的铜、铅、镉和锌,铝合金中铋、铜和铅的测定;借溶出法已用于海水痕量铜、镉和锌,二氧化锆中痕量铜、
Department of Chemistry, Xiamen University, Xiamen, the second analytical instrument factory trial success 75-3A Mercury Membrane Electrode Fast Polarography. The instrument uses integrated circuit devices. The instrument includes a linear scanning circuit, an electrode system and a recording current section. Use two op amps as a linear scan circuit and current amplifier. Platinum ball mercury silver mercury-plated mercury film electrode instead of mercury electrodes for conventional polarographic analysis can also be used for dissolution analysis. Determination of bismuth, copper and lead in copper, lead, cadmium and zinc, and aluminum alloys in lead and zinc, copper and lead used in copper alloys by conventional polarographic analysis of such electrodes and instruments in the relevant units; Has been used for trace amounts of trace amounts of copper, cadmium and zinc in seawater, trace amounts of copper in zirconium dioxide,
