The nitrogen content in vanadium nitrogen alloy powder was detected using the EMGA-830 oxygen nitrogen hy-drogen analyzer according to the standard"Vanadium nitrogen alloys-Determination of nitrogen content-Inert gas melting thermal conductivity method" ( GB/T24583.2-2019),and the influencing factors of the experimental detection were clari-fied. The results showed that the detection results of the combination scheme of tin bladder and nickel basket in the standard did not meet the actual nitrogen content value in the sample;According to the given values of the combination scheme of nickel bags and tin particles in the standard,the testing effect is significantly better than that of the combination of tin bags and nickel baskets. However,under this combination,different amounts of co solvent added,equipment analysis power,and sample quality all have a certain impact on the testing results. The EMGA-830 oxygen nitrogen hydrogen analyzer was used to test vanadium nitrogen alloy powder samples. The best experimental parameters for determining the nitrogen content in vanadium nitrogen alloy powder were nickel capsule loading of 0.05 g,co solvent tin particles of 0.4 g,and equipment a-nalysis power of 6 kW.
