| 摘 要： | 抗氧剂对于保持喷气燃料的储存稳定性和改善替代燃料的质量至关重要.气相色谱-质谱-选择离子联用技术(GC-MS-SIM)可以定量检测燃料油中的受阻酚抗氧剂,利用单柱法和二维中心切割法两种方法检测了燃料中不同抗氧剂的含量,试验结果表明,两种方法都能够有效地测定喷气燃料中酚类抗氧剂的含量,其中中心切割法在抗氧剂检出限、定量检测限以及测定结果线性相关性方面均优于单柱法.

| Abstract: | Antioxidant additives are important to keep the storage stability in fuels and improve the quality of alternative fuel.Hindered phenolic antioxidant additives in fuels can be quantified by GC-MS-SIM.This paper uses single column and two column heart-cutting method to detect different antioxidant additives in fuels.It was demonstrated that both methods can effectively quantify hindered phenolic antioxidant additives in fuels.Heart-cutting method offers significant advantages over the single column in detection limits,quantitation limits and the linear correlation. |
