采用裂解气相色谱-质谱(Py GC/MS)联用法对不同企业(如A、B、C和D等)生产的卷烟胶之Py(裂解)产物性能进行了对比和分析,并探讨了样品、载气、升温速率和Py温度等因素对分析结果的影响。研究结果表明:当样品取样量为2 mg、载气为氦气、升温速率为20 K/ms和Py终温为900℃时,卷烟胶的主要Py产物为乙酸,其次为稠环芳烃、苯系物及烯烃类等;不同企业生产的卷烟胶之Py产物类型有一定差异,仅C企业生产的卷烟胶之Py产物中可检测到少量醛类、酯类物质,B、D企业生产的卷烟胶之Py产物中乙酸含量相对较高。
The performance of Py (cracked) products of cigarette gum produced by different enterprises (such as A, B, C and D) were compared and analyzed by Py GC / MS. The samples, Carrier gas, heating rate and Py temperature and other factors on the analysis results. The results show that when the sample volume is 2 mg, the carrier gas is helium, the heating rate is 20 K / ms and the final temperature of Py is 900 ℃, the main Py product of cigarette gum is acetic acid, followed by condensed aromatic hydrocarbons, benzene Department of products and olefins, and so on; Py products produced by different companies have different types of Py products, only a small amount of aldehydes and esters can be detected in the Py product of cigarette gum produced by C enterprise, cigarettes produced by enterprises B and D Acetic acid content of Py Pyrene is relatively high.
