摘要
本文基于固相微萃取技术(SPME,Solid-PhaseMicroextraction),建立了运用新型氮化碳纤维涂层固相微萃取(HS-SPME-GC-MSMS)结合计算机质谱数据库及气味分析数据库检索定性,用正构烷烃校正内标保留指数,多种挥发性物质SCAN和MRM同时扫描,并利用内标标准曲线对化合物进行定量的检测酶解牛油香气组分的分析方法。对比了两种不同规格(氮化碳纤维涂层和Carbon-PMS(碳-聚二甲基硅氧烷)涂层)固定相吸附涂层对检测结果的影响。研究表明,得益于二维共轭聚合物层状结构以及较大的比表面积,氮化碳纤维涂层对挥发性气相组分的吸附效果要比Carbon-PMS涂层更好,更能满足现代化气味分析实验室多样、快速、高效的实验要求。氮化碳纤维涂层在吸附萃取挥发性组分方面具有较大的潜力。
Based on solid-phase microextraction technology(SPME), this paper established An analytical method for the detection of aroma components of beef tallow by busing of new Carbon nitride fiber coated solid-phase microextraction(HS-SPME-GC-MSMS)combined with computer mass spectrum database and odor analysis database to search qualitatively, correct the i nternal standard retention index with normal paraffins, and scan simultaneously volatile substances with SCAN and MRM mode.The effects of stationary phase ads orption coatings on the test results were compared between two different kinds of material(carbon nitride fiber coating and Carbon-PMS(carbon-polydimethylsiloxane) coating). The results show that Benefited from the layered structure of the two-dimensional conjugated polymer and the large specific surface area, the adsorption effect of carbon nitride fiber coating on volatile vapor components is better than that of Carbon-PMS coating, which can better meet the diverse, fast and efficient experimental requirements of modern odor analysis laboratories. Carbon nitride co ating have great potential in adsorption and extraction of volatile components.
