An analytical method of measuring carbon in V2O3 with infrared absorption carbon-sulphur analysis unit(CS-344) is established through a number of comparative tests, work curve correction and standard addition process. The method and carbon analysis data are reliable through rechecking. Determination results show that relative standard deviation ≤ 7.0% is achieved by accuracy test within the range of 0.02%~0.05% C in V2O3. Through a number of tests it is identified that Ammonium salt present and carbon content in V2O3 decreased gradually with longer time are major influencing factors on accurate measurement carbon with the infrared method.
