| 摘 要： | 气相色谱仪检定结果的不确定度主要来源于流速稳定性、柱箱温度稳定性、基线噪声、定量重复性和标准物质进样量的不确定度。以TCD检测器为例进行分析,对气相色谱仪检定结果的不确定度进行评定,相对扩展不确定度为5%。

| Abstract: | The main sources of uncertainty of verification for gas chromatography were stability of flow,stability of oven temperature,baseline noise,repetition of qualitative analysis and inputting amount of standard substance.The detector TCD was taken as example,the relative expanded uncertainty of verification of chromatography was 5%. |
