HH-JSQVII 汽油甲缩醛快速检测专用毛细管柱的详细资料
汽油甲缩醛快速检测专用毛细管柱甲缩醛是一种无色易挥发可燃液体，是现行的车用汽油标准中不得添加的有害物质。添加有甲缩醛的汽油会导致发动机里塑料或橡胶制成的密封件发生化学反应，破坏发动机的密封性。与正规汽油相比，甲缩醛燃烧值较低，发热量不够高，也会导致油耗增加。
采用微板流路控制(Deans Switch)中心切割技术,建立了分析汽油中甲缩醛含量的二维气相色谱法。仪器价格高昂，操作复杂，普通化验室很难配置。
滕州市浩瀚色谱仪器技术服务有限公司，，以科学发展为为指导，，，色谱工程研究所，分析与测试中心3个科研单位，研发出《汽油甲缩醛快速检测专用毛细管柱》，直接进样，单柱分析了汽油中甲缩醛含量，结果满意，。实验结果表明,甲缩醛含量(w)在0.01%~5.00%范围内时标准工作曲线呈良好的线性关系,线性相关系数达0.999 9,试样加标回收率为97.83%~104.11%,6次重复测定的相对标准偏差小于2.00%,甲缩醛检出限为0.003%(w)。该方法准确,适合测定车用汽油中的甲缩醛含量。该方法具有分析速度快、重复性好、分析成本低等优点。

Special capillary column for rapid detection of gasoline methylal
Methylal is a colorless, volatile and flammable liquid, and it is a hazardous substance that must not be added to the current automotive gasoline standards. Gasoline added with methylal will cause a chemical reaction of the plastic or rubber seals in the engine, which will damage the engine's airtightness. Compared with regular gasoline, methylal has a lower combustion value and insufficient heat generation, which will also increase fuel consumption.
