| 摘 要： | 研究了多维气相色谱分析技术检测含有内标物MTBE（甲基叔丁基醚）汽油中含氧化合物（醇类和醚类）的方法。通过实验，考察了分流比、阀切换时间等因素对实验结果的影响，确定了最佳实验条件；同时对该方法的准确度和精密度进行验证，结果表明，该方法具有很好的精密度，加标回收率在90％-102％之间，样品分析周期为20min。由此可见，采用多维气相色谱分析技术，可以快速、准确地测定清洁汽油中的含氧化合物。

| Abstract: | A method was established for determining oxide - containing compound in clean - gasoline with DME by muti - GC. By experiments, the influence of the split - flow ratio and exchange - time of valve to result was exanined and then the best experiment conditions were determined. The method has been proved to be reliable and accurate. The recovery range is 90 % - 102 %. One analysis can be completed in 20 minutes. The method is rapid, accurate and highly sensitive. |
