这项工作的目的是比较直接注入Q-TOF质谱仪通过三个不同的大气压源，电喷雾电离（ESI），大气压化学电离（APCI），大气压光电离（APPI）耦合到一个高分辨率的Q-TOF质谱仪。一个复杂的混合物的多环芳烃和氧多环芳烃，获得后的空气氧化的荧蒽在矿物基板上，被用来比较不同的电离能力，这些来源。在这里，我们提出了使用所有来源的分析方法。最终的目标是提供背景选择最合适的来源，以分析复杂的有机混合物，如那些遇到污染的土壤，水，沉积物，以及石油。
The objective of this work was to compare direct infusion in a Q-TOF mass spectrometer through three different atmospheric pressure sources, electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photoionization (APPI) coupled to a high resolution Q-TOF mass spectrometer. A complex mixture of PAH and oxy-PAHs, obtained after the air oxidation of fluoranthene on mineral substrates, was used to compare the different ionization abilities of these sources. Here, we propose analytical methods for the use of all sources. Final goal was to provide background to the choice of the most appropriate source in order to analyze complex organic mixtures as those encountered in polluted soils, water, sediments, as well as in petroleum.
