摘　　要：使用Vario MACRO cube型元素分析仪测定硝化棉氮含量。不锈钢材质炉体的两级燃烧管设计保证了硝化棉在大样品量下的完全燃烧及燃烧安全性,最大样品量可达85 mg。该方法具有简便快速、自动化程度高、结果准确性高等优点。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.
