摘要
基于“新工科”创新型人才培养的要求,将最新科研成果用于研究生教学,建立了集样品提取、净化于一体的顶空固相微萃取技术(HS-SPME)联合气质联用法,准确分析太湖饮用水源地水样中9种臭味物质。该方法利用无有机溶剂消耗、样品用量少、富集效率和自动化程度高的顶空固相微萃取技术。该方法的教学充分发挥了前处理技术与仪器分析联合自动化的优势,突破了传统样品前处理的繁琐步骤,展现了环境样品中痕量有机污染物的自动化分析方法,实现了教学与科研的深入融合。
Based on the requirements of the cultivation of innovative talents in new engineering,the previous scientific research results of teachers are applied to the experimental teaching of graduate students,and the headspace solid phase microextraction(HSSPME)combined with selective ion detection mode GC-MS method is established to accurately analyze 9 odorous substances in water samples from the drinking water source of Taihu Lake,which integrates the sample extraction and purification.This HS-SPME technology has some advantages with low/solvent-free consumption,less sample consumption,high enrichment efficiency and high automation.The experimental teaching gives full play to the advantages of the joint automation of pretreatment technology and instrument analysis,breaks through the tedious steps of traditional sample pretreatment,shows the automatic analysis method of trace organic pollutants in environmental samples,and realizes the in-depth integration of teaching and scientific research.
