摘要
介绍氮中低含量CO气体标准物质定值的方法,对气体滤光相关分析法进行了探讨,给出了该方法的实验条件和精密度。将气体滤光相关分析法的测量值与重量法配制值、气相色谱法分析值进行了比对。气体滤光相关分析法重现性好,分析结果准确、可靠。
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.
