| Abstract: | The Kjeldahl is a general analysis method for determining nitrogen in rubber.This article presents the method for determination of nitrogen in rubber by autonitrogenmetric analyzer.Comparing with chemical analysis,the accuracy and precision to test nitrogen content by instrumentation analysis is as good as the Kjeldahl.In addition,the instrumentation analysis has advantages of high automatic control degree,without transferring of samples.So,a simple,fast and accurate analysis method is confirmed for detemination of nitrogen contents in batch samples of rubber by auto-nitrogenmetric analyzer. |
