【摘要】：采用全二維氣相色譜-質(zhì)譜聯(lián)用儀(GC×GC-MS),通過優(yōu)化程序升溫和調(diào)制周期,建立了噴氣燃料裂解產(chǎn)物中芳烴的定性定量分析方法。該方法對(duì)多環(huán)芳烴(PAH)同分異構(gòu)體具有良好的分離能力。利用MS檢測(cè)器譜庫(kù)檢索結(jié)果、芳烴標(biāo)準(zhǔn)品及相關(guān)的文獻(xiàn)報(bào)道,對(duì)噴氣燃料裂解產(chǎn)物中常見的單環(huán)芳烴、二環(huán)芳烴、三環(huán)芳烴及四環(huán)芳烴等共27種芳烴進(jìn)行了準(zhǔn)確定性,并利用外標(biāo)GC×GC-FID法對(duì)其進(jìn)行定量。定量結(jié)果表明,芳烴含量均隨著裂解產(chǎn)氣率的增加而增大,當(dāng)裂解產(chǎn)氣率達(dá)到22%時(shí),二環(huán)芳烴開始產(chǎn)生,且其含量隨著裂解產(chǎn)氣率的增加呈指數(shù)形式增加。該方法與傳統(tǒng)的氣相色譜-質(zhì)譜相比,具有更好的分離及定性能力,可應(yīng)用于復(fù)雜樣品的分離及其定性定量分析。
[Abstract]:A method for qualitative and quantitative analysis of aromatic hydrocarbons in pyrolysis products of jet fuel was established by means of a full two-dimensional gas chromatography-mass spectrometer (GC 脳 GC-MS) and optimization of temperature programmed and modulation periods. This method has good separation ability for (PAH) isomers of polycyclic aromatic hydrocarbons (PAHs). By using MS detector spectral library search results, aromatics standard products and related literature reports, 27 aromatics, such as monocyclic aromatic hydrocarbons, dicyclic aromatic hydrocarbons, tricyclic aromatic hydrocarbons and tetracyclic aromatic hydrocarbons, which are common in pyrolysis products of jet fuel, were accurately identified. The method of external standard GC 脳 GC-FID was used to quantify it. The quantitative results showed that the aromatics content increased with the increase of pyrolysis gas production rate. When the pyrolysis gas production rate reached 22, the dicyclic aromatics began to produce, and its content increased exponentially with the increase of pyrolysis gas production rate. Compared with the traditional gas chromatography-mass spectrometry, this method has better separation and qualitative analysis ability, and can be applied to the separation and qualitative analysis of complex samples.
