| Abstract: | The nitrogen content in nitrocellulose was determined by using the Vario MACRO cube element analyzer. The design of two stage combustion tubes made with stainless steel assures the complete combustion of nitrocellulose under large sample amounts and the safety of combustion. The maximum sample amount can reach 85 mg. The method possesses the advantages such as simplicity, rapidity, high degree of automation, high accuracy of results, and so on. |
