An improved hydrogenation—microcoulometric method for the determination of nitrogen in organic materials including coal and heavy residual oils

Abstract

Abstract The reliability of the Dohrman hydrogenation-microcoulometric system for the determination of nitrogen in organic products has been improved by replacing the troublesome platinum-black indicator electrode by a glass electrode. This involves a simple modification of the microcoulometer. The applicability of the method has been extended to cover coal and asphaltenes by using a basic flux. These samples previously gave low results.
