| Abstract: | The method of the determing value for CO standard gas of low content in the nitrogen was introduced, and the gas filter correlation (CFC) analysis method was discussed. The GFC conditions and precision of the method was given, The measurement result of GFC analysis, the value from the gravimetric method and the value from gas chromatography were observed and compared. The test result proved that the reproducibility of GFC analysis method was better and the analysis results were accurate and reliable. |
