采用选择离子监测（ＳＩＭ）模式作为气相色谱／质谱法（ＧＣ／ＭＳ）检测方式测定了某超高压液压油中两种添加剂２，６－二叔丁基对甲酚的质量比和磷酸三苯酯的质量比。测得的校正因子Ｆ值和添加剂质量比均有较高的精确度。还对ＳＩＭ 模式中有关离子的选择作了简单的探讨。
The mass ratio of 2,6-di-tert-butyl-p-cresol and two kinds of additives in an ultrahigh-pressure hydraulic oil were determined by selective ion monitoring (SIM) mode as gas chromatography / mass spectrometry (GC / MS) Ester mass ratio. Measured correction factor F value and additive mass ratio have higher accuracy. The selection of ions in the SIM mode is also briefly discussed.
