本文报导了有机化合物中氯、溴元素的微量自动分析法.通过使用椭圆形的氧瓶和装在同一瓶中的银电极,使样品(3～5毫克)燃烧、吸收和库仑滴定能连续进行.每次测定约5分钟.测定误差小于0.5%.

An automatic method is described for the microdetermination of chlorine and bromine in organic compounds.Using an oval oxygen flask in combination with a silver electrode system, the combustion, absorption and coulometric titration of the sample (3 to 5 mg) are carried out successively in the same vessel.Each determination takes ca.6 min.and the absolute error is below 0.5%.
