SP-3400气相色谱仪与GC-2400便携式色谱仪对比观测

气相色谱法具有分离效率高、分析速度快、分析灵敏度高等特点,基于SP-3400气相色谱仪及GC-2400便携式色谱仪的工作原理、工作方式、工作条件等,对庐江地震台2套色谱仪观测结果进行对比,分析存在的误差,通过H2高值异常现象,探讨色谱仪运行及维护工作。初步分析结果表明:2套色谱仪定量分析精度均较高,观测数据相关性较好,因不同仪器生产厂家所提供的色谱工作站软件不同,部分测项观测结果存在一定差异。

The observational comparing of SP-3400 gas chromatograph with GC-2400 gas chromatograph

Gas chromatography has the characteristics of high separation efficiency, fast analysis speed and high analytical sensitivity. Based on the working principle, working method and working condition of SP-3400 gas chromatograph and GC-2400 portable chromatograph, to compare the results of two sets of chromatographs of Lujiang Seismic Station, to analyze the existence of the error. Through the high value of hydrogen anomalies, to explore the operation of the chromatograph and maintenance work. The results of the preliminary analysis show that the accuracy of the two sets of chromatographs is high and the correlation between the observation data is good. Because of the different chromatographic workstation software provided by the different instrument manufacturers, there are some differences in the observation results.
