Abstract：Standard gas calibration equipment for the simultaneous determination of O, N, H and Ar was built by combining the gas circuit of pulse heating and time-of-flight mass spectrometer gas analyzer with the six-port injection valve which was normally used in chromatogram. Two processes of purging of quantitative tube and injecting of standard gas can be converted smoothly. Using the equipment, calibration curves of low content O, N, H and Ar were established, and thestability was tested. Samples were analyzed by these calibration curves, and the results matched with the certified values. From the results, it was showed that the problem of Ar reference materials in ultra low content range can be solved by this equipment, and Ar can be analyzed quantitatively. The established calibrating curve by standard gas calibration setup can be used for metal materials analyzing, and good linearization of the calibrating curve can be got.
