电子捕获检测器（ＥＣＤ）是气相色谱仪的一个重要组成部分，在使用过程中易受到污染，而无法正常工作。本文主要介绍国产Ｎｉ６３源代替进口原装Ｎｉ６３源安装后，根据仪器性能指标要求对ＥＣＤ的灵敏度、基线稳定性进行调试及其结果，表明国产Ｎｉ６３源代替进口原装Ｎｉ６３源气相色谱仪的灵敏度、基线稳定性符合仪器规定的标准。
Electronic Capture Detectors (ECDs) are an important part of gas chromatographs that are easily contaminated and inoperable during use. This paper introduces the domestic Ni63 source instead of imported original Ni63 source installation, according to the requirements of the instrument performance indicators ECD sensitivity, baseline stability of the commissioning and the results show that the domestic Ni63 source instead of imported original Ni63 source gas chromatograph sensitivity, baseline stability In line with the provisions of the instrument standards.
