摘要
根据现行的NB/SH/T0663和SH/T0713标准检测车用汽油中氧和苯含量,由于采用不同的填充柱和检测器,需配置2台不同的气相色谱仪的情况,提出了使用传统的阀切换系统与毛细管路控制技术相结合,利用一台气相色谱仪和双氢火焰监测器(FID),一次进样,同时测定汽油中的氧和苯含量的改造方案,分析了可行性,可提高工作效率,节约检测成本,适合目前石油产品质量判断和产品验收。
In view of the current situation that 2 gas chromatographs need to be configured to detect the oxygen and benzene content in gasoline,because different filling columns and detectors are used respectively,resulting in low work efficiency and high detection cost,the method by combining a traditional valve switching system and a capillary tube control technique,using a gas chromatograph and a double hydrogen flame ionization detectors( FID) to determine the content of oxygen and benzene in gasoline simultaneously through once sampling is presented.The feasibility of the method is analyzed. This detection method can help to greatly improve the work efficiency and save the detection cost.
