摘要

将大气压光电离(APPI)、电喷雾(ESI)、实时直接分析(DART)多种电离源和傅立叶变换离子回旋共振质谱(FT-ICR MS)联用对石油芳烃样品中的未知化合物进行研究。通过高分辨质谱的精确质量，结合碰撞诱导解离(CAD)技术，经分析并与文献标准物质谱图比对，推断未知物为三(2，4-二-叔丁基苯基)磷酸酯(TDTBPP)，并研究了其在不同大气压电离源中的电离特性。APPI谱图中主要为［M+H］+峰，同时存在M.+峰。ESI谱图中主要为［M+Na］+(不加甲酸)或［M+NH4］+峰(加甲酸)。DART谱图中主要为［M+NH4］+峰，而EI谱图中基峰为m/z 57(叔丁基)，次强峰为［M-CH3］+峰。

Abstract

An unknown compound in petroleum aromatics was analyzed by Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS) coupled with atmospheric pressure photoionization(APPI)，electrospray ionization(ESI) and direct analysis in real time(DART) ionization.It was determined as tris(2，4-di-tert-butylphenyl)phosphate(TDTBPP) by the accurate mass of FT-ICR MS and collision activated dissociation(CAD).The characteristic spectra of TDTBPP in multiple ionization sources were demonstrated.The result indicated that the main mass peak in APPI was ［M+H］+，and M.+ was also present.The main mass peak in ESI was ［M+Na］+(without formic acid) or ［M+NH4］+(with formic acid)，and the main mass peak in DART was ［M+NH4］+.APPI FT-ICR MS could be used to determine the polycyclic aromatic hydrocarbons(PAHs) with relatively higher molecular weight which could not be determined by gas chromatography-mass spectrometry.
