卷烟烟气中多环芳烃的分析

Analysis of PAHs in Cigarette Smoke

通过自制吸收装置及高效吸收液对烟气中有机成分进行充分吸收,采用溶液吸收法对样品进行富集采集,最后利用气相色谱-质谱联用技术的高分离和高定性等优点对卷烟烟气中的成分进行全谱分析。结果表明:卷烟烟气中所含20多种物质,浓度较大为7种,多数为对人体伤害较大和致癌的有机物质。

The Organic components of smoke are absorbed efficiently by the absorption equipment, which is made by ourselves. It collects sample by means of solution-absorbed and makes use of GC/MS which is high-qualitative and high-isolation to analysis the content of smoke in cigarette at last.
