摘要
使用国产氧氮分析仪(ON2008)就钒氮合金中高氮的分析方法进行了研究,提出了采用高纯氩气作载气、无需使用助熔剂、直接在坩埚中加入样品、使用专用坩埚盖的分析方法。该方法大大降低了分析成本,样品准备简单、便捷,称样量可达0.1 g以上。方法用于实际生产中,其精度满足分析要求。
Methods to analyze the nitrogen content of vanadium- nitrogen alloy were discussed with ON2008 oxygen and nitrogen analyzer （made in China）. Referred to the reported documents, a new simplified method was presented. The new method chose argon as into the crucible, and a graphite cover designed the carrying gas, no flux is needed, the sample is directly put specially is used. The new method cut down the analyzing cost and simplifies the preparation of sample, the weighing of sample could be more than 0.1 g. The method was applied in the analysis of VN production, and the accuracy of result could match the requirement.
