库仑分析法,或称电量分析法,其基本原理是法拉第电解定律。它是一种快速、灵敏、准确的分析方法,近年来国际上发展较快,已广泛用于有机元素分析,特别在超微量(样品量在1毫克以下)、自动分析方面成效卓著。我国也有单位从事这方面的研究,取得可喜成果。目前所分析的元素已包括碳、氢、氯、溴、碘、氮、硫、 Coulomb analysis, or electricity analysis, the basic principle is Faraday’s law of electrolysis. It is a fast, sensitive and accurate analytical method. In recent years, it has developed rapidly in the world and has been widely used in organic elemental analysis, especially in the ultra-trace amount (sample size below 1 mg) and automatic analysis. Some units in our country are engaged in this aspect of research and have achieved gratifying results. The elements analyzed so far have included carbon, hydrogen, chlorine, bromine, iodine, nitrogen, sulfur,
