Abstract： To overcome the difficults of the analysis of inert gas argon and the scarcity of argon reference materials, a kind of standard gas calibration device was designed and quantitative pipes of different volumes were prepared to conduct calibration by feeding standard gas through standard gas injection interface. Simultaneously, a novel determination method of argon in titanium alloy and nano-alloy powder was established by pulse inert gas fusion-mass spectrometry. The results indicated that the absolute quality of argon showed good linear relationship with ion count of Ar+（m/z = 40）spectral line. The linear range was 0.000 010%-0.10% and the detection limit was 0.000 006%. This proposed method was applied to the determination of argon in titanium alloy and nano-alloy powder. The results were consistent with those obtained by pulse fusion thermal conductivity method or theoretical calculated value, and the relative standard deviations were all less than 14%.
